a tabletop in the shape of a trapezoid has an area of 5,217 square centimeters. its longer base measures 123 centimeters, and the shorter base is 65 centimeters. what is the height

 55.5 cm

Step-by-step explanation:

Height = 2a/(b1 + b 2)

Where a = area and b1, b2 are the 2 bases.

Base length = (2a/h) – b

Where a = area and b = base, and h is the height.

Area = mh

Where m = median and h = height.
