Q. The rectangular-shaped doctor's office has an area of 120 square feet and a perimeter of 44 feet. What are the dimensions of this office space?

A. Do I add just add 120 by 44??
12.. so 10 & 12?
No.
A = L * W
P = 2L + 2W
Yes. You're right. :-)
Oh! So I have to mulpite somethin next go get 44?
Perimeter = (2 * L) + (2 * W)
Substitute 10 and 12 for length and width. Do you get 44?
What's substitute? We never learned yet..
P = (2 * 10) * (2 * 12)
P = ?
I don't know how but I got 480
I'm sorry -- but I have a typo in the perimeter formula.
This is the correct formula.
P = (2 * 10) + (2 * 12)
