The area of a rectangular field is equal to 300 square meters. Its perimeter is equal to 70 meters. Find the width and length of this rectangle.

L × W = 300 : area , L is the length and W is the width. 2 L + 2 W = 70 : perimeter L = 35 - w : solve for L (35 - W) × W = 300 : substitute in the area equation W = 15 and L = 20 : solve for W and find L using L = 35 - w.
