You are planning to paint the entire front of your barn, excluding the door, which is 7 ft x 3 ft.  How many square feet will you be painting?

The area of a trapezoid is the sum of the bases divided by 2, all multiplied by the height.

Here, the two bases are 12 and 20, and the height is 15.

Find \(\frac{12+20}{2}\times 15\), which is the area of the barn.

Finally, subtract the door size. I think you can do that.

 

You are very welcome!
