A trapezoid is given with base lengths of 10m and 14m, and a height of 9m.
It is required to find the area of the trapezoid.
Recall that the area of a trapezoid with base lengths b₁, b₂, and height h is given by:

Substitute b₁=14, b₂=10, and h=9 into the formula:

Hence, the required area is 108 m².
The answer is 108 m².
