Question

Determine the area of the composite shape.

Answer 1

132 ft²

Explanation:

The shape is composed of a rectangle and a triangle.

Area of the shape = area of rectangle + area of triangle

Area of rectangle = L*W

L = 12 ft

W = 8 ft

Area of rectangle = 12*8 = 96 ft²

Area of triangle = ½bh

b = 8 ft

h = 21 - 12 = 9 ft

Area of triangle = ½(8*9) = 36 ft²

Area of the shape = 96 + 36 = 132 ft²
