Answer:

  10 inches

Step-by-step explanation:

Use the formula for the area of a trapezoid. Fill in the given information and solve for the unknown.

  A = 1/2(b1 +b2)h

  50 in² = (1/2)(3 in +7 in)h

  50 in²/(5 in) = h . . . . . . . . . . divide by the coefficient of h

  10 in = h

The height of the trapezoid is 10 inches.
