You are designing a rectangular pet pen for your new baby puppy. You have 35 feet of fence barrier. You decide that you would li
Zielflug [23.3K]

Hello from MrBillDoesMath!

Answer:

l = 12 feet,  w = 5.5

Discussion:


Let w be the width of the pen and "l" the length. From the problem statement

l = w + 6.5  and the perimeter, P, of the fence -= 35.

Now the perimeter of the rectangle is given by the formula

P = 2l + 2w.  

In our case, P = 35 and l = w + 6.5 so the equation becomes:

35 = 2(w+6.5) + 2w =>

35 = 2w + 13 + 2w =>

35 = 4w + 13  =>         (subtract 13 from both sides)

35-13 = 4w  =>

22 = 4w =>

w = 22/4 = 5.5 feet

As, l = w + 6.5, l =  5.5  + 6.5 = 12 feet


Thank you,

MrB
