Answer:
Area of the trapezoid = 90 square feet
Explanation:
Area of a trapezoid with bases b₁, b₂ and height h is given by the formula,
Area of a trapezoid =
![(1)/(2)(b_1+b_2)h](https://img.qammunity.org/2022/formulas/mathematics/high-school/jr71y6c248fwmk3s578p2uotzb2emm7sub.png)
By substituting the given values in the formula,
Area =
![(1)/(2)(6+9)12](https://img.qammunity.org/2022/formulas/mathematics/high-school/oyhaaasux7bcly8k43xhvt5v5siin5g0dm.png)
=
![(180)/(2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/r2qvecjezslcz4dwa7qxsg6bdiyvzlz1bt.png)
= 90 square feet
Therefore, area of the trapezoid = 90 square feet
