Question

A rectangle has a height of x and a width of 7x-4

Answer 1

length is 7 times the width

Explanation:

Answer 2

The area of the entire rectangle is
`7x^2-4x`.

Explanation:

Given : A rectangle has a height of x and a width of 7x – 4.

To find : Express the area of the entire rectangle ?

Solution :

The height of the rectangle l=x.

The width of the rectangle b=7x-4.

The area of the rectangle is

`\text{Area}=l* b`

`\text{Area}=x* (7x-4)`

`\text{Area}=7x^2-4x`

Therefore, the area of the entire rectangle is
`7x^2-4x`.
