Question 892478
w = width
3w + 8 = length  {lenght is 8 more than 3 times width}


Perimeter of a rectangle = 2(width) + 2(length)


2w + 2(3w + 8) = 88 {substituted into perimeter formula}
2w + 6w + 16 = 88 {used distributive property}
8w + 16 = 88 {combined like terms}
8w = 72 {subtracted 16 from each side}
w = 9 {divided each side by 8}
3w + 8 = 35 {substituted 9, in for w, into 3w + 8}


width = 9 inches
length = 35 inches
