In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data
w = 8 ft
l = 15 ft
total area (paint) = ?
Step 02:
rectangle area
A = l * w
A1 = 15 ft * 8 ft = 120 ft²
circle area
A = π r²
half circle area
A = (π r²) / 2
A2 = (π * (4ft)²) / 2
A2 = 25.13 ft²
total area = A1 + A2 = 120 ft² + 25.13 ft² = 145.13 ft²
The answer is:
They will used 145.13ft² of paint.
