+7cm->
I 22 cm
9 cm
15 cm
Work out the total area of the shape.

Answer 1

Area of shape = 187 cm²

Explanation:

Given:

Length of rectangle = 15 cm

Width of rectangle = 9 cm

Height of triangle = (22-9) cm = 13 cm

Base of triangle = (15-7) cm = 8 cm

Find:

Area of shape

Computation:

Area of shape = Area of rectangle + Area of triangle

Area of shape = (l)(b) + (1/2)(b)(h)

Area of shape = (15)(9) + (1/2)(8)(13)

Area of shape = 135 + 52

Area of shape = 187 cm²
