Question

A rectangle has a height of 4x4x4, x and a width of 3x+13x+13, x, plus, 1. Express the area of the entire rectangle.

Answer 1

Area= 12x^2+4x

Explanation:

Answer 2

Given:

The rectangle has a height of 4x and the width of
`3x+1`

We need to determine the area of the entire rectangle.

Area of the rectangle:

Let us determine the area of the rectangle.

The area of the rectangle can be determined using the formula,

`A=length * width`

Substituting the value length = 4x and width =
`3x+1` in the above formula, we get;

`A=4x(3x+1)`

Let us remove the parenthesis by multiplying the term 4x within the bracket, we have;

`A=12x^2+4x`

Thus, the entire area of the rectangle is
`12x^2+4x`
