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?
What are you talking about?
Please post the whole problem, and I'll try to help you.
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
Please answer anyone you guys there?
Ahh -- I see now.
P = 2L + 2W
P = (2 * 8) + (2 * 6)
P = 16 + 12
P = 28 feet
28 * 0.85 = $23.80
