Answer:
≈ 64.26 ft²
Explanation:
The figure is composed of a rectangle ( middle section ) and 2 semicircles which can be combined into 1 complete circle.
area of rectangle = 12 × 3 = 36 ft²
The circle has diameter = 12 - 3 - 3 = 12 - 6 = 6 ft
then radius r = 6 ÷ 2 = 3 ft
area of circle = πr² = 3.14 × 3² = 3.14 × 9 = 28.26 ft²
Then
area of figure = 36 + 28.26 = 64.26 ft²
