Hi Debbie, First of all you need to know how many square feet are in an acre. You can use Google for this, just type 1 acre in square feet into the Google search window to find the answer. Suppose the rectangle is $x$ feet wide then the area is $300 \times x$ square feet. But Google has told you the area in square feet so you can solve for $x.$ Penny | |||||||||||||||
