How many bags of Weed /amp; Feed fertilizer would you need to cover a rectangular yard that measured 40 feet by 90 feet, if each bag covered 4000 square feet?
First things first find the area for this rectangular yard. 40 x 90=3,600 (area) you'll basically need 94% of the bag. also you have to figure out the height of the area where the feed fertilizer is going to go.
