Joy is helping her father to build rectangular deck that measures 14ft by 19ft. Find the area of the deck using a mental strategy. Explain your thinking.

If we draw the deck, we have length 19ft and width 14ft. Then to find the area of the deck we get:

$19*14 ft = 266 ft^2$

$(14*20)-(14*1) = 280-14 ft^2 = 266 ft^2$

The foot is a unit for measuring length. The foot is one of the Imperial units and U.S. customary units. One foot contains 12 inches, while a foot is equal to 12 inches, and a yard is made up of 3ft.
