Frequently Asked Questions

How do you find length and width from area and perimeter alone?

Rearranging the area and perimeter formulas produces a quadratic equation, whose two roots are the length and width.

What are the length and width of a rectangle with area 48 and perimeter 28?

The length is 8 and the width is 6.

Is it always possible to find real length and width values this way?

No, if the perimeter is too small relative to the area, the quadratic equation has no real solution, meaning no such rectangle exists.
