    The width of the mural is 8ft ... how'd I get that? First, you need to know the formula for the area of a rectangle ... A = LxW. The length is 9, so what number multiplied by 9 equals 72? 8! 9x8=72. The perimeter equals 35 feet. How'd I get that? The width and length should both be multiplied by 2. 9x2=18 and 8x2=16. 18+16=35 feet!
