I really don't know where to start here. --- Start with the formula: P = 2(L+W) --- P/2 = (L+W) ==== Now double length and width: Multiply both sides by 2 to get: P = (2L+2W) ; The perimeter doubled --- Multiply both sides by 3 to get: 3(P/2) = 3L + 3W : The perimeter is multiplied by 3 etc. Cheers, Stan H. ============
