Question

The area of a trapezoid is 36.36 square centimeters. One base of the trapezoid is 14.8 centimeters. Its height is 3.6 centimeters.

Which sentence explains how to find the length of the other base of the trapezoid?


Divide the area by the base. Multiply the quotient by 2. Then subtract the height from the product.


Add the base and the height. Then subtract the sum from the area.


Divide the area by the height. Multiply the quotient by 2. Then subtract the known base from the product.


Multiply the base times the height. Then subtract the product from the area.

Answer 1

The third answer (Dividing the area by the height, multiplying the quotient, etc) is correct.

If we multiply by the height, we receive an expression equal to the sum of the bases divided by two.  Multiplying by two, we now have the sum of the bases.  Subtracting one base gives the length of the other base.
