Frequently Asked Questions
How do you find the perimeter when you only know the area and one side?
Divide the area by the known side to find the missing side, then apply the standard perimeter formula to both sides.
What is the perimeter of a rectangle with an area of 48 and one side of 8?
The missing side is 6, giving a perimeter of 28 units.
Why is knowing just the area not enough on its own?
The same area can be produced by many different length and width combinations, so at least one side length is also needed.
