How to Find the Width of a Rectangle - wikiHow
RECTANGLE: Length (l) by Width (w) Area = l * w. Perimeter = 2*1 + 2*w. Maximum area for four sides: Each side is ¼ of the perimeter (p). This is also a square. Area = (¼p)(¼p) Uniform Width: Add 2x to the length and width. Area = (1 + 2x) (w + 2x) Maximum area for three sides: One side of the rectangle is already given like a river or wall.
