Question

Can someone please help me out but no links please

Answer 1

The area of the shape is the same as

Area of the rectangle - Area of the semi-circle.

From the picture, the length and the width of the rectangle are 11 and 8 respectively so the area of the rectangle will be 8 * 11 = 88 unit^2.

From the picture, the diameter of the semi-circle is 8 and so the radius is 4.

Using the area of a semicircle formula:

A = $\frac{\pi r^2}{2}$

A = $\frac{3.14*16}{2} = 3.14*8 = 25.12$ unit^2.

Hence, the area would be 88 - 25.12 = 62.9 unit^2
