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.

Step-by-step 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:
