The formula for finding the area of a rectangle is:

A = 2h + 2w

You know the area and the width. Solve the equation for the height. If you post your answer, we'll be glad to check it.

The area of a rectangle is (length)(width)

so 86.4 = 12(length)

length = 86.4/12

Check your answer by multiplying what you got by 12
