Step-by-step explanation:
Area of Rectangle = Length x Width
Area of Top Rectangle =
[tex]22 \times (31 - 18) \\ = 22 \times 13 \\ = 286 {ft}^{2} [/tex]
Area of bottom Rectangle =
[tex]18 \times 9 \\ = 162 {ft}^{2} [/tex]
Area of Composite figure = Area of top Rectangle + Area of bottom rectangle
[tex] = 286 + 162 \\ = 448 {ft}^{2} [/tex]
