Find the area of the figure. PLEASSEEEEEEEE!!!!!!!!

allochka39001 [22]

Given:

side length = 6 ft

To find:

The area of the figure

Solution:

Area of the square = side × side

= 6 × 6

Area of the square = 36 ft²

Diameter of the semi-circle = 6 ft

Radius of the semi-circle = 6 ÷ 2 = 3 ft

Area of the semi-circle = $\frac{1}{2} \pi r^2$

$$=\frac{1}{2} \times 3.14 \times 3^2$

Area of the semi-circle = 14.13 ft²

Area of the figure = Area of the square - Area of the semi-circle

= 36 ft² - 14.13 ft²

= 21.87 ft²

Area of the figure = 21.9 ft²

The area of the figure is 21.9 ft².
