Question

Area = 22 m 18 m 16 m

Answer 1

First divide the parts where it is a rectangle and semicircle.

Find the area of the rectangle:

A = length × breadth

A = 18m × 16m

A = 288m²

Then find the area of the semi-circle. We know that the area of a circle is πr² and half that area gives you the area of a semi-circle: πr²/2

A = πr²/2

A = π(6)²/2

A = 18πm² or 56.549m²

Total Area = 288m² + 18πm²

                                OR

                    288m² + 56.549m² = 344.549m²
