Area = (length) times (width)Length = (area) divided by (width)Width = (area) divided by (length)

To find the relationship in width and area you can use the formula area/length = width. To find the area of a room you multiple the length by the width.

For a rectangle or square, Area = Length * Width So Length = Area / Width.

you need length and width length multiply width = area length + length + width + width = perimeter

Divide the area by the width and it will give you the length.
