Given:
The length of a rectangle is 3, more than twice the width.
Required:
We need to find the area of the rectangle.
Explanation:
Consider the area of the rectangle formula.
[tex]A=lw[/tex]Let w be the width of the rectangle.
[tex]twice\text{ the width =2w and more than 3 means add 3.}[/tex]The length of the rectangle is
[tex]l=2w+3[/tex]Substitute l =2w+3 in the formula.
[tex]A=(2w+3)w[/tex][tex]A=2w^2+3w[/tex]Final answer:
