A group of friends is roping off a soccer field in a back yard. A particular full-size soccer field is a rectangle with a length of 100 yards and a width of 50 yards. To fit the field in the back yard, the group needs to reduce the size of the field so its perimeter is 60 yards.
What is the Area of the soccer field in the back yard?
Answer:
200 ft
The original perimeter would be 300, so divided by 5, it would be 60. 100/5 is 20, 50/5 is 10. 20*10 is 200.

Matthew had to make a bridge for his math class. It had to be at least 1 1/2 feet long. Harold made a bridge that was 2/13 times as long as Matthew’s. Write and solve an equation that will help you figure out how long Harold’s bridge was. Explain the steps you took to solve the problem.
Answer:
Step-by-step explanation:
2 / 13 = 15.38% or 15.38..... If Matthew's bridge is 1 1/2 feet long which is 45.72cm then 45.72 + 15.38 = 61.1cm > convert into feet > 1.55194 ft.
