A tabletop in the shape of a trapezoid has an area of 4,944 square centimeters. Its longer base measures 127 centimeters, and the shorter base is 65 centimeters. What is the height?
First.....the area of a trapezoid is (B1 +B2)/2 * HEIGHT B1= 127 CM B2 = 65 CM
Soooo....substitute into the equation:
4944 cm^2 = (127+65)/2 * HEIGHT
Now....just solve for Height.....can you do that? If not, you are in a class that is too advanced for you.
