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.
Perimeter = 2 x (width + length)⇒ 12 = 2 x (width + length)⇒ width + length = 6⇒ the rectangles could be:1 by 52 by 43 by 3[A square is a rectangle with equal sides.]
The factor pairs are the length and width of the rectangles.
The answer is 576cm.
The following rectangles have a length and width that make an area of 36: 1 x 36; 2 x 18; 3 x 12; 4 x 9; 6 x 6
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.
The set of whole numbers is infinite; hence, the number of rectangles that meet your specifications is infinite, as well. Are you sure you have the question right?

You can't. There are an infinite number of possible rectangles with a given area.
Length x Width
The expression is L - 3.
The width is half the length: The perimeter is twice the length plus twice the width. If the perimeter is 3 times the length, twice the width must be the length.
