Each cow needs 4 square yards of pasture and there are 3 feet in a yard so 4 yards^{2} = 4 (3 feet)^{2} = 4 × 3^{2} feet^{2} = ^{}36 square feet. How many 36 square feet regions are there in 10,800 square feet? Draw a diagram for the next part. The brown fence is 5 feet inside the boundaries on each side and gives a new pasture area that is L feet long by W feet wide. How long is L? How long is W? What is the area L × W of the smaller pasture? How many 36 square feet regions are there in this smaller pasture? Penny
