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

  = w = 1.9748ft (rounding off as directed)
