Answer:

72cm²

Step-by-step explanation:

Hello!

The formula for area of a trapezoid: [tex]A = \frac12(b_1 + b_2)h[/tex]

We find the average of the bases, and multiply it by the height.

Plug in the values and solve

[tex]A = \frac12(b_1 + b_2)h[/tex]
[tex]A = \frac12(9 + 15)6[/tex]
[tex]A = \frac1224(6)[/tex]
[tex]A = 12(6)[/tex]
[tex]A = 72[/tex]

The area of the trapezoid is 72cm²
