Question 548043
perimeter (the distance around) is two lengths plus two widths ___ P = 2L + 2W


for this rug ___ "The length is 2 times as long as the width" ___ L = 2W


since they are equal, you can substitute L for 2W in the perimeter equation


P = 2L + (L) ___ 78 = 3L ___ L = 26


substituting 26 for L ___ (26) = 2W ___ 13 = W
