I hope this helps! :)
Step-by-step explanation:
Formulas:
For the Rectangle... <em>bh = a</em>
For the Semicircle... 1/2 × πr²
Step 1:
Solve the area for the rectangle:
<em>bh = a</em>
10 × 12 = 120
a = 120 ft²
Step 2:
Solve the Area for the Semicircle:
1/2 × πr²
1/2 × 3.14 = 1.57
Radius = Diameter ÷ 2
10 ÷ 2 = 5
Radius = 5
1.57 × 5²
1.57 × 5 × 5
= 39.25 ft²
Step 3:
Add the two areas together:
120 + 39.25 = 159.25 ft²
