Dave had a section of his roof damaged by hail, so he needs to replace the shingles. The roof section can be represented by trapezoid JKLM. How many square feet of shingles must he order?

To determine how many square feet of shingles Dave needs to order, we need to calculate the area of the trapezoid JKLM.

To calculate the area of a trapezoid, we use the formula:

Area = (base1 + base2) * height / 2

Let's assume the lengths of JK and LM are the bases and the width KL is the height. If you have these measurements, you can substitute them into the formula to find the area.

Once you have the area, you will know how many square feet of shingles Dave needs to order to cover the damaged section of his roof.

(B+b)/2 * h
