The perimeter of a rectangle is 132 feet. The ratio of the length to the width is 10: 1. Find the length and the width.

The correct answer is: Length= 60ft, width = 6ft

Given : Perimeter of a rectangle is 132 feet. 
Ratio of the length to the width is 10: 1.
Let the length (l) = 10x and width(b) = 1x
We know that Perimeter of rectangle =2(l+b)
2 ( 10x + 1x) = 132feet
22x = 132
x = 6 feet
Length of rectangle = 10x = 10 6 = 60 feet and
Width of rectangle = 1x = 6feet
Thus , the length and the width are 60feet and 6feet respectively.
