Answer 1

A = 108 m²

Explanation:

the figure is composed of a rectangle (left ) and a triangle (right )

calculate the area of both and then sum them

area of rectangle = length × width

length = 15 m , width = 6 m

area = 15 × 6 = 90 m²

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

here b = 6 m and h = 21 - 15 = 6 m

area =
`(1)/(2)` × 6 × 6 = 3 × 6 = 18 m²

total area A = 90 + 18 = 108 m²
