Question

What is the area of the composite figure? I know how to find the area of a triangle but not a circle

Answer 1

The composite figure consist of two figure one triangle with base b = 8 ft and height h = 7 ft and other semi circle with diameter of d = 8 ft.

Determine the area of composite figure.

`\begin{gathered} A=(1)/(2)\cdot b\cdot h+(\pi(d)^2)/(8) \\ =(1)/(2)\cdot8\cdot7+(\pi(8)^2)/(8) \\ =28+3.14\cdot8 \\ =28+25.12 \\ =53.12 \end{gathered}`

So area of composite figure is 53.12 feet square.
