To find the area of the composite figure, we need to break it down into separate shapes and then add their areas together.
The composite figure consists of a rectangle with dimensions 3.5 ft by 4 ft and a semicircle with a radius of 1.5 ft.
Area of the rectangle:
Area = length x width
Area = 3.5 ft x 4 ft
Area = 14 square feet
Area of the semicircle:
Area = 1/2 x π x r^2
Area = 1/2 x π x (1.5 ft)^2
Area = 1/2 x π x 2.25 ft^2
Area ≈ 3.534 square feet
Total area = Area of rectangle + Area of semicircle
Total area ≈ 14 square feet + 3.534 square feet
Total area ≈ 17.534 square feet
Therefore, the area of the composite figure is approximately 17.534 square feet.
WRONG
I apologize for the error in the previous calculation. Let's correct it:
Area of the rectangle:
Area = length x width
Area = 3.5 ft x 4 ft
Area = 14 square feet
Area of the semicircle:
Area = 1/2 x π x r^2
Area = 1/2 x π x (1.5 ft)^2
Area = 1/2 x π x 2.25 ft^2
Area ≈ 3.534 square feet
Total area = Area of rectangle + Area of semicircle
Total area ≈ 14 square feet + 3.534 square feet
Total area ≈ 17.534 square feet
Therefore, the correct area of the composite figure is 17.534 square feet. Thank you for your patience.

To find the area of the composite figure, we need to calculate the area of the rectangle and the area of the half-circle (semicircle) separately and then add them together.
Area of the rectangle:
The dimensions of the rectangle are 3.5 ft by 4 ft.
Area = Length x Width
Area = 3.5 ft x 4 ft
Area = 14 square feet
Area of the semicircle:
The radius of the semicircle is 1.5 ft.
Area = 1/2 * π * r^2
Area = 1/2 * π * (1.5 ft)^2
Area ≈ 1/2 * 3.14159 * 2.25 sq ft
Area ≈ 3.534 sq ft
Total Area = Area of rectangle + Area of semicircle
Total Area = 14 sq ft + 3.534 sq ft
Total Area = 17.534 sq ft
Therefore, the area of the composite figure is approximately 17.534 square feet.
