Answer:
18 square meters
Explanation:
The area of a trapezoid is given by the formula ...
A = 1/2(b1 +b2)h
The bases are the parallel line segments, and the height is the perpendicular distance between them.
A = (1/2)(7 m + 5 m)(3 m) = 1/2(12 m)(3 m) = 18 m^2
The area of the trapezoid is 18 square meters.
