Question

The area of a rectangle is 56cm squared. If the length of the rectangle is doubled, what is the new area?

Answer 1

`112cm^2`

Explanation:

The formula for the area of a rectangle is length times width:

`A=LxxW`

In our case, we have:

`56=LxxW`

So what happens if we double the length? We get:

`A=2xxLxxW`

And so in our example we'll have

`56=LxxW=>2xxLxxW=112`
