Answer:

Area of shaded region = 70.88 unit

Explanation:

Given:

Height of shaded region = 12 units

Width of shaded region = 8 units

Find:

Area of shaded region

Computation:

Radius of semi circle = Width of shaded region / 2

Radius of semi circle = 8 / 2

Radius of semi circle = 4 unit

Area of shaded region = Area of rectangle - Area of Semi circle

Area of shaded region = [l x b] - [πr² / 2]

Area of shaded region = [12 x 8] - [(3.14)(4)² / 2]

Area of shaded region = 96 - [(3.14)(16) / 2]

Area of shaded region = 96 - 25.12

Area of shaded region = 70.88 unit
