Question

Find the area of the composite shape

Answer 1

Known :

d = h triangle = 8 m

b triangle = 12 m

r = ½ d = ½ × 8 = 4 m

Asked :

Area = ...?

Answer :

A = A ½ circle + A triangle

= ½πr² + ½bh

= (½ × 3,14 × 4²) + (½ × 12 × 8)

= 25,12 + 48

= 73,12 m²

So, the area is 73,12 m³

Hope this is helpful and useful :)
