Need to find width of a Rectangular Garden....

Question

The Perimeter is 36 ft.  The length is 10 ft. What is the Width of the rectangle? 

Answer 1

The length is 10.

 

Let w = the width

 

Perimeter of 

Rectangle = 2L + 2W   ... W = width, L = Length

          36 = 2(10) + 2w

          36 = 20 + 2w

   36 - 20 = 2w

          16 = 2w

           8 = w

 

The width is 8 ft.

Answer 2

w represents the width

p = 2(l + w)

 

36 = 2(10 + w)

18 = 10 + w       divide both sides by 2

8 = w                 subtract 10 from both sides
