Question

A tabletop in the shape of a trapizoid has an area 8607 square centimeters. its longer base measures 123 centimeters, and the shorter base is 105 centimeters what is the height?​

Answer 1

286.94 cm

Explanation:

Data:

Area = 8,607

b1 = 105

b2 = 123

Area = 1/2 * (b1 + b2) * h

h = 2 * Area/b1 + b2

h = 2 * 8,607/105 + 123

h = 286.94 cm

I'm not sure if it's right but that's what my calculator gave me.
