If two similar rectangles have the widths 16m and 14cm what is the ratio of the perimiters?
These are not similar rectangles so there is no obvious candidate for the ratio. Is it ratio of lengths (sides, perimeter, diameter), or ratio of area?
To determine if the ratio of length to width for two rectangles is proportional, you need to compare the ratios of their lengths to widths. If the ratios are equal, then the rectangles are proportional. For example, if Rectangle A has a length of 10 units and a width of 5 units (ratio of 10:5 or 2:1), and Rectangle B has a length of 20 units and a width of 10 units (ratio of 20:10 or 2:1), then the rectangles are proportional because the ratios are equal.
If the 'ratio' (length/width) of one rectangle is the same number as (length/width) of the other one, then the two rectangles are similar.
