Find the area of the trapezoid.

12 m
16 m
11 m

To find the area of a trapezoid, you can use the formula:

A = (1/2) * (a + b) * h

Where:
- a and b are the lengths of the two parallel sides
- h is the height (the perpendicular distance between the two parallel sides)

In this case:
a = 12 m
b = 16 m
h = 11 m

Plugging in the values:
A = (1/2) * (12 + 16) * 11
A = (1/2) * 28 * 11
A = 14 * 11
A = 154 square meters

Therefore, the area of the trapezoid is 154 square meters.
