Question

Find the area of the figure.

8 m
15 m
Rounded to the nearest tenth, the area is
square meters.

Answer 1

145.1 square meters

Explanation:

The figure is composed of a rectangle and a semicircle.

Therefore, area of the figure = area of the rectangle + area of the semicircle

✔️Area of the rectangle = L*W

L = 15 m

W = 8 m

Area of rectangle = 15*8 = 120 m²

✔️Area of semicircle = ½(πr²)

r = ½ of 8 = 4 m

Area of semicircle = ½*π*4²

Area of semicircle = 25.1327413 m²

✔️Area of the figure = 120 + 25.1327413 = 145.132741 ≈ 145.1 m² (nearest tenth)
