Question

Find the area of the following figure

Answer 1

A = 280 ft²

Explanation:

the figure is composed of a rectangle and a triangle.

area of rectangle = 20 × 10 = 200 ft²

area of triangle =
`(1)/(2)` bh ( b is base and h the height )

b = 20 and h = 18 - 10 = 8 , then

area =
`(1)/(2)` × 20 × 8 = 10 × 8 = 80 ft²

total area A = 200 + 80 = 280 ft²
