Perimeter L w L w 2L 2w.To find the area of a rectangle, just multiply the length times the width You want to find the maximum area, so substitute the perimeter equation (eq1) into the area equation (eq2).This critical value is the length that will give the maximum area. Then once you have the length, plug it into eq1 to get the width.
