A football stadium is being built and the builders need to determine the perimeter of the entire building. The stadium has a shape of a rectangle that measures 120 yards long by 80 yards wide. Semicircles extend from both 80-yard sides. Find the exact and approximate perimeter of the entire stadium and find the exact and approximate area of the entire stadium.

Answer 4

You have the perimeter of a rectangle = 2l + 2w (l = length, w = width)

You have 2 semicircles which is just one complete circle, and the perimeter (circumference) of a curcle is just 2(pi)(radius) or just (pi)(diameter).

Answer 5

For the area,

Area ofm a rectangle = length x width

area of a complete circle (2 semi-circles) = (pi)(radius)^2
