Area of the rectangle is [tex]6u^{2}[/tex]
How to find area of rectangle if the vertices are given:
Let the vertices be or the given vertices:
A [0,-4]
B [-1,-3]
C [2,0]
D [3,-1]
Area of rectangle is twice the area of triangle, i.e. if the area of rectangle is ABCD and area of triangle is ABC.
Area of triangle is given by determinant:
Area of triangle = 1/2 [x1, y1]
1/2 [x2, y2]
1/2 [x3, y3]
1/2 [x4,y4]
Putting all the values in this format we will get :
Area of triangle = 1/2 [0×-4]
[-1×-3]
[2×0]
Because we have assume 0 as x1 and -4 as y2
-1 as x2 and -3 as y2
2 as x3 and 0 as y3
By solving that equation we will get:
1/2[ −4 0 1]
[−3,1,1]
[0,−2,1]
=1/2(−4⋅(1⋅1+1⋅2)−0+1⋅(6−0))
=1/2|-6|= [tex]3u^{2}[/tex]
= -3=[tex]3u^{2}[/tex]
= [tex]6u^{2}[/tex]
In a two-dimensional plane, a triangle's area is the space it encloses. Known for having three sides and three vertices, a triangle is a closed shape. The sum of the spaces occupied by a triangle's three sides is known as its area. Half of the product of a triangle's base and height is the usual formula for calculating its area.The area that is included within the perimeter of a flat object or figure is generally considered to be the definition of the word "area." The square units used for measuring are square meters as the standard unit (m2). There are already established formulas for calculating the area of squares, rectangles, circles, triangles, etc.

if 5y -4 = 21, then y=
5y-4 = 21
Add 4 on both sides to isolate y. (get rid of -4)
5y = 25
Divide 5 on both sides to solve for y.
y = 5
Answer:
Y is equal to 5
Step-by-step explanation:
5y - 4 = 21
5y = 21+4
5y = 25
Y = 25 ÷5
Y = 5

hemisphere at a height of 328 meters. One of the popular tourist attractions in Auckland is
to jump off the top of the tower or to walk around the outside observation deck. On vacation, Sydney was walking around the outside of the Sky Tower and threw an apple with an initial velocity of 40 mph or 17.882 meters per second.
Part A: How many seconds will it take the apple to hit the ground (ignoring air resistance)? Round your answer to the nearest tenth of a second.
Sophie is ordering a taxi from an online taxi service. The taxi charges $3.50 just for the pickup and then an additional $1.25 per mile driven. How much would a taxi ride cost if Sophie is riding for 4 miles? How much would a taxi ride cost that is m miles long?
Answer:
8.50 dollars
Step-by-step explanation:
1.25 per mile ==> 5 dollars for 4 miles
5+3.50(original cost) = 8.50

If each of the following quadrilaterals are trapezoids, find the missing measures. Show your work.
Answer:
Step-by-step explanation:
Since this is a trapezoid, then we have TS is parallel to QR
so we have:
[tex]\angle T+\angle Q = 180^\circ\\\angle S + \angle R = 180^\circ[/tex]
since[tex]\angle T = 91^\circ, \angle R = 27^\circ[/tex]
The measure of angle Q is 89 degree
The measure of angle S is 153 degree
Help me please. It’s for my geometry class and I don’t understand it.
Answer:
the answer is 29 degrees
Step-by-step explanation:
180 is the total of all the angles added together so if you subtract the 122 from 180 and divide by 2 you can get 29 for both and if you add it all together you should get 180 :)
Answer:
29
Step-by-step explanation:
pretty ez, so like a triangle got 180 degress total. what u gota do my man, is substract 122 from it. And u get 58 and they both are equal so u divide by 2 and u get 29.
Find the area of the green region
Answer:
Step-by-step explanation:
so imagine each of the 4 white spaces are like 1/4 of a circle. In this case 3.5 cm would be the radius(r) of the circle, agree?
the area of a circle is pi * r²
pi =~3.14
circle area = 3.14 * (3.5 * 3.5)
circle area = 3.14 * 12.25
circle area = 38.465 cm²
Ok, now that we have the white area, the green area is basically the full area of the square minus the white area, agree?
the side of the square is 3.5 + 3.5, which is 7 cm
square area = 7 * 7
square area = 49 cm²
green area = 49 - 38.465
green area = 10.535 cm²

Answer:
[tex]\frac{\frac{3}{4} mi}{x}[/tex]=[tex]\frac{1 mi}{5,280 ft}[/tex]
Step-by-step explanation:
First find the perimeter of the rectangle to see the total length
2([tex]\frac{1}{8}[/tex])+2([tex]\frac{1}{4}[/tex])
[tex]\frac{3}{4}[/tex]
Then, because you are converting from miles to ft, you can use the ratio of miles/feet to determinte the correct ratio for the perimeter.
The correct ratio is [tex]\frac{1 mi}{5,280 ft}[/tex]
To set these ratios equal to eachother, first see that one side of the equation has miles as the unit, the other side has miles/feet, so you must divide the perimeter by feet to set the ratios equal to eachother.
Therefore, the correct equation is [tex]\frac{\frac{3}{4} mi}{x}[/tex]=[tex]\frac{1 mi}{5,280 ft}[/tex]

Which equation represents a constant of proportionality of 25? *
12 points
F. x + 25 = y
G. 25x = y
H. x − 25 = y
J. 5x = y
Answer:
G
Step-by-step explanation:
An equation of proportionality has the form
y = kx ← k is the constant of proportionality
y = 25x ← has this form with k = 25
y = 5x ← has this form with k = 5
The required equation is y = 25x with k = 25 → G

Answer:
A --> 57
Step-by-step explanation:
you can find the linear pair on YH by getting 180 and subtracting it by 106 giving 74. Add 74 and 49 to get 123. The rule with triangles is that all angles inside one equal 180 so get 180 and subtract it by 123 which gets you 57.
