Question

Given the rectangle above, what is a possible representation of the area?

Answer 1

The area of a rectangle is it's width multiplied by it's length.

For this rectangle, it's lenght is:

`L=x+5`

And it's width is

`W=x`

When you multiply both of them you get the area A:

`A=L\cdot W=(x+5)\cdot x`

It can also be writen as:

`A=x^2+5x`
