Divide the width by the length when both are measured in the same units.

You find the ration by creating a fraction from the fators and then reducing the fraction to the lowest common denominator. The resulting reduced fraction is the ratio. For Example. A length of 10 feet and a width of 5 feet 10/5 reduces to 2/1 so 2:1 is the ratio of length to width
You measure the length, L, in some units (inches, centimetres, whatever), measure the width, W, in the same units and then calculate L/W.
The ratio of width to length is 34, so W = 34*L The area of a rectangle is L * W, so using the ratio we get L * 34*L = 108 cm2 34*L2 = 108 L = SQRT (108/34) = 1.78 cm W = 60.6 cm
If Length * Width = Area, then Area ÷ width = Length
Area = (length) times (width)Length = (area) divided by (width)Width = (area) divided by (length)
