Question 822778: On my worksheet it says, You are making a sign. The length is 10 times the width. The area of the sign is 39 sq.ft. What is the width. I tried using the formula area=length*width. Substituted the numbers 39=w(10w). Then, I got 39=w^2*10. I don't know what to do after.

Hi,
On my worksheet it says, You are making a sign.
The length is 10 times the width. The area of the sign is 39 sq.ft.
What is the width.
area=length*width
39=w(10w)
39=w^2*10 |Good Work
3.9 = w^2
sqrt%283.9%29 = w = 1.9748ft (rounding off as directed)
