This figure is a rectangle with a semicircle cut out of it. To find the area, you will first need to find the area of the rectangle and subtract the area of the semicircle.
Area of the rectangle.
6ft×6ft=36 square feet
Area of semicircle
The diameter is 6, so the radius is 3.
1/2 ×π(3)^2=1/2 ×9π=4.5π
36-4.5π≈21.9 square feet, rounded to the nearest tenth.
The answer is 21.9 square feet, rounded to the nearest tenth.
