Question

the diagram represents a sports ground. the bends are semicircle. calculate the area of the sports ground. give your answer correct to the nearest square metre

Answer 1

8,163 square meter

Explanation:

The area of the sports ground = area of rectangle + 2(area of semicircles)

= L*W + 2(½*πr²)

L = 120 m

W = 51 m

r = ½ of 51 = 25.5 m

Plug in the values

Area of the sports ground = 120*51 + 2(½*π*25.5²)

Area = 6,120 + 2,042.82062

Area = 8,162.82062 ≈ 8,163 square meter
