Question 61336: hpw do you find the polnomial for the area l*w
Answer by funmath(2933) (Show Source): You can put this solution on YOUR website!
You need to provide more information. l*w is the area of a rectangle.
Sometimes they will tell you something like, the length is 5 more than the width.
The you would say:
let width be: x
Then length is: x+5
Then A=l*w is:
A=x(x+5)
A=x^2+5x
:
Hope that helps.
For the problem in your book,
let length be: 3x
Let width be:3x-3
A=l*w
A=3x(3x-3)
A=3x(x)+3x(-3)

Happy Calculating!!!
