Question

The measure of the length of a rectangle is 5x and the measure of the width is 3x.

Find the measure of the area.

Exponents can be entered in your answer in the form "(x^2)".

Answer 1

`Area=15x^2` square units.

Explanation:

The given rectangle has the following dimension:

`l=5x`

and

`w=3x`

The area of a rectangle is

`Area=l* w`

We substitute the dimensions in terms of
`x` into the formula for the area to get;

`Area=(5x)* (3x)`

This simplifies to give us;

`Area=15x^2` square units.
