First, divide the figure into 2 shapes. A triangle (on the top), and a rectangle (on the bottom).
Find the area of each figure.
Triangle- Base: 9 ft Height: 8 ft
Area = base x height / 2
Area = 9 x 8 / 2
Area = 72 / 2
Area = 36 ft squared
Rectangle- Simple enough: length x width
Area = 9 x 7
Area = 63 ft squared
Add- 36 + 63 = 99 ft squared
