A table top in the shape of a trapezoid has an area of 2250 square centimeters and the shorter base is 80 centimeters. The longer base is 100 centimeters. What is the height

The area of a trapezoid has a formula of:
Area = (a + b) h / 2

Using the formula, we can easily find the height of the trapezoid.
Area = (a + b) h / 2
2250 = (80 + 100) h / 2
2250 = 180h / 2
2250 = 90h
h = 25 centimeters

So the height of the trapezoid is 25 centimeters.
