Answer:
9.57 ft²
Explanation:
assuming the diigram attached is similar to the one required to complete the question,
From the diagram
Area of the window = Area of the rectangle+ Area of the semi circle.
A = lw+πr²/2................ Equation 1
Where A = area of the window, l = length of the rectangle, w = width of the rectangle, r = radius of the semi circle.
From the diagram,
Given: l = 4 ft, w = 2 ft, r = w/2 = 2/2 = 1 ft.
Constant: π = 22/7
Substitute these values into equation 1
A = (4×2)+(22/7×1²/2)
A = 8+1.57
A = 9.57 ft²
