<PRE><B>Question 260638</B>
The length of a rectangle is 8 centimeters less than 3 times the width. 
a. Write a polynomial that represents the area of the rectangle. 
b. Find the area of the rectangle when the width is 10 centimeters.

Let the width be  x

Three times width = 3x
8 cms less than 3x  = 3x-8 = length

Area of rectangle = Length * width

                  = (3x-8)* x
                  = 3x^2-8x 

If width = 10 cms
3*(10)^2 * 10
3*100*10
3000 sq. cms
