Cindy has 34 meters of fencing. She
plans to fence in a rectangular dog run
that is 4 meters wide.
[Remember, the formula for the
perimeter of a rectangle (the distance
around) is p= 2L + 2w, where L=
length and w = width.]

34=p

4=W

13=L

Step-by-step explanation:

4 meters wide means width

34 is the total because that is how much Cindy has  

Now we use the formula

34=2L+2(4)

34=2L+8

Subtract 8 from both sides.

26=2L

Divde by 2 from both sides.

13=L

Now that we have found L plug it in to check.

P=2(13)+2(4)

P=26+8

P=34
