Question

Shana wants to use all 62 feet of the fencing she has to make a rectangular run for her dog. She decides to make the length of the run 20 feet. She writes and solves the equation 2l + 2w = 62 to find the width of the run.

Answer 1

Width of the run is
`11` feet

Explanation:

Perimeter of a rectangular field

`= 2 (length) + 2( width)\\= 2 l + 2w\\`

On solving the above equation, we get -

`2l + 2w = 62\\2 (20) + 2w = 62\\w = (62 -40)/(2) \\w = 11\\`

Width of the run is
`11` feet

Answer 2

You have asked no question.

I am ASSUMING you want to know how to solve the equation to learn the width.

2L + 2W = 62

2(20) + 2W = 62

40 + 2W = 62

2W = 22

W = 11
