Question 946530
A rectangle has a perimeter of 48 in. The length of the rectangle is 6 in. What is the width?

Let the width be "w", Given length = 6 in, while Perimeter (P) = 48 in
Formula for perimeter (P) of a rectangle is 
    P = 2l +2w
Plugging the known values we get
  48 = 2.6 + 2w
 48-12 = 2w
  36= 2w  

w = 36/2 = 18
Hence width of rectangle is 18 inches.
