Picture included about solving polynomials!

With this problem, you should first look at the equation for the area of a trapezoid. That is A = (1/2)(B1 + B2)*H. We know what A, B1, and B2 are so you just need to solve for height. So, based on the equation:

Next, you would have:

Next solve for h by dividing the polynomials like so:

Using long division you get:
