Question

If the area of a rectangle is 12.88 square cm and its length is 5.6 cm, then what is the width?

Answer 1

`2.3 cm`

Explanation:

The area of a rectangle is its length times its width, or `l*w`
You said the area is `12.88 cm^2`, so we know `l*w=12.88 cm^2`
Plugging in the given length, we get `5.6*w=12.88`
Dividing both sides by `5.6` to solve for `w`, we find out that `w=2.3 cm`.
