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
