Answer:
5 cm
Explanation:
The formula for the area of a trapezoid gives a relation that can be used to find the height.
A = 1/2(b1 +b2)h . . . . b1, b2 are base lengths, h is the height
__
Filling in the given information, we have ...
25 cm² = 1/2(3 cm +7 cm)h
25 cm²/(5 cm) = h = 5 cm . . . . . . . divide by the coefficient of h
The height of the token is 5 cm.
