Answer:
105 ft²
Step-by-step explanation:
Divide the figure into 3 rectangles and a triangle.
Rectangle 1
Area of a rectangle = width × length
= 4 × 15
= 60 ft²
Rectangle 2
Area of a rectangle = width × length
= (5 - 3) × (15 - 6)
= 2 × 9
= 18 ft²
Rectangle 3
Area of a rectangle = width × length
= 3 × 5
= 15 ft²
Triangle 4
Area of a triangle = 1/2 × base × height
= 1/2 × (12 - (15 - 6 - 5) × (5 + 4 - 3 - 3)
= 1/2 × 8 × 3
= 1/2 × 24
= 12 ft²
Total Area
Total Area = 60 + 18 + 15 + 12
= 105 ft²
