Answer 1

5 ft

Explanation:

You can find the missing dimension by using the area formula and solving it for the missing dimension.

__

A = 1/2(b1 +b2)h . . . . . . . . . . . . formula for the area of a trapezoid

25.5 ft² = 1/2(7 ft +3.2 ft)h . . . . with the given numbers filled in

(25.5/5.1) ft = h = 5 ft . . . . . . . . . divide by the coefficient of h

The height of the trapezoid is 5 ft.
