a dollar bill has an area of 15.86 square inches. If a dollar bill is 2.6 inches long, how wide is it?
Please explain how you got please!!!

You know that area of a rectangle is A=lw. If you know the area to be 15.86 square inches and the length to be 2.6 inches, you would set up the equation as follows and solve:
A=lw
15.86=(2.6)(w)
You would divide by 2.6 to get w by itself.
You're length would be 6.1 inches.
For you to check for future reference, multiply 2.6(6.1) and you would get 15.86 square inches, which would be your area you started with. 
wouldn't your width be 6.1 inches?

Yes, I'm sorry. That was a typo. It would be your width

thank you soo soo much!!! =)
