A L W where A is the area L is the length W is the width and means multiply. The formula is where equals the length of the rectangles diagonal equals the length of the rectangle and equals the width of the rectangle. A lw Area.
Therefore the perimeter of a rectangle 58 cm.
The given rectangle has a length that is units longer than its width. Where a a and b b are the length and width of the rectangle respectively. D sqrt l 2b 2. This equation is represented by ALW.
