I have this paper and it talks about chad and Claire and the rectangular base and when it said the least expensive thing I got 8 by 6 with the cost \$23.80 it's right but I forgot how I got my answer a little help please?

Claire and chad want to design a rectangular pen for their new puppy to have an area of 48 square feet. Fencing costs \$0.85 per foot.
What are the dimensions and the cost of the least expensive pen Claire and chad could build, assuming the side lengths are whole numbers. Explain. I got 8 by 6 and it's right but I forgot how I got the answer for the cost help me

Ahh -- I see now.

P = 2L + 2W

P = (2 * 8) + (2 * 6)

P = 16 + 12

P = 28 feet

28 * 0.85 = \$23.80

the dimensions are 8x6. if you multiply the cost \$.085 times 48 you get \$40.80.

Oh I get it now thank you so much wow u r a lifesaver thank you very much I really appreciate it

Donna -- the area is 48 square feet. Gabby needs the perimeter to find out how much fencing is needed.

That was for miss sur by the way

You're welcome, Gabby.
