Question

A seat cushion is shaped like a trapezoid. The shorter base of the cushion is 3 inches greater than the height. The longer base is 2 inches shorter than twice the height. Write the polynomial that can be used to the area of the cushion.

Answer 1

A = (b1 +b2)/2 * h
.. = ((h +3) +(2h -2))/2 *h
.. = (3h +1)/2 * h
.. = (3/2)h^2 +(1/2)h
