Thank you!

The easiest way to go about solving this, is to find the area of each shape and add together. Start on the left rect.: 5x8=40 Middle rect: 12*8 = 96 Right rect: 13*8 = 104 The triangles will be: 30 each. Add those together to get 40+96+104+30+30 = 300in^2.

This is even easier than the last! Starting from left to right then top and finally bottom rectangle: 6*8 = 48 11*8 = 88 6*8 = 48 11*8 = 88 11*6 = 66 11*6 = 66 Add those together to get: 404ft^2. Do you see where I am getting the numbers from?
