Question

The length of a rectangle is 3 more than twice the width. The area of a rectangle isgiven by the formula A = /x w. Which of the following equations could be used tofind the area?

Answer 1

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.

$A=lw$

Let w be the width of the rectangle.

$twice\text{ the width =2w and more than 3 means add 3.}$

The length of the rectangle is

$l=2w+3$

Substitute l =2w+3 in the formula.

$A=(2w+3)w$$A=2w^2+3w$

Final answer:
