a tabletop in the shape of a trapezoid has area an of 6,550 square centimeters. Its longer base measures 115 centimeters, and the shorter base is 85 centimeters. what is the height?

To find the missing dimension of the tabletop, the height, you will use the formula for finding the area of a trapezoid and solve for the missing height.

A = 1/2 h (b1 + b2)
 6550 = 1/2 h (115 + 85)
6550 = 1/2 h (200)
6550 = 100h
100      100

655 = h

The height is 655 cm.
