Firstly, you need to find the area of the bottom "rectangle" by multiplying 20 by 14 to get 280 Sq. Ft. You then add 14 and 7 to get the length of the bottom of the upper "rectangle" to get 21. Now you continue in the steps of the bottom to multiply 24 by 21 to get 504 Sq. Ft. In the end, you add them together to get the total area to be 784 Sq. Ft.
