Question

Find the area of the composite figurep

Answer 1

53.12 sq ft

Explanation:

For triangle:

Base (b) = 8 ft

Height (h) = 7 ft

For semicircle:

Radius (r) = 8/2 = 4 ft

Area of the composite figure = Area of triangle + Area of semicircle.

`= (1)/(2) bh + (1)/(2) \pi {r}^(2) \\ \\ = (1)/(2) (8)(7) + (1)/(2) (3.14)(4)^(2) \\ \\ = (4)(7) + (3.14)(8) \\ \\ = 28 + 25.12 \\ \\ = 53.12 \: {ft}^(2)`
