The side length of Tom's square garden was 72 ft. He used ½ of the garden for growing roses. What area of his garden was left? The remaining area of his garden is ft²

We will solve as follows:
*We calculate the area and divide it by two, that is:
[tex]A=72^2\Rightarrow A=5184[/tex][tex]\Rightarrow A_l=\frac{5184}{2}\Rightarrow A_l=2592[/tex]So, the area left was 2592 squared feet.
