Answer:
B
Explanation:
Split into 3 shapes: the left most triangle, the middle rectangle and then the right most triangle on its side.
The height of the left triangle is the same as the height on the right: 6.
Left triangle area = (1/2) * base * height = (1/2) * 5 * 6 = 15
Height of rectangle is also 6.
Rectangle area = base * height = 8 * 6 = 48
Right most triangle area = (1/2) * base * height = (1/2) * 4 * 6 = 12
12 + 48 + 15 = 75 square feet
