1. Given:

   The ratio of the length to the width of a rectangle is 10:6.

   Perimeter = 160 meters

   To find:

   The measure of the width.

   Solution:

   Let the length and width of the rectangle be 10x and 6x respectively.

   Perimeter of a rectangle is

   

   where, l is length and w is width.

   Putting P=160, l=10x and w=6x, we get

   

   

   

   Divide both sides by 32.

   

   

   Now,

   

   

   

   Therefore, the width of the rectangle is 30 meters.
