Add up the lengths of all the sides. Since there are two pair of equal sides, just take each the length and double it and then the width and double it. Now add those two numbers. If the length is L and the width is W, the perimeter is 2L +2W
square, rectangle, rhombus, parallelogram
The perimeter of the larger polygon will have the same ratio to the perimeter of the smaller as the ratio of the corresponding sides. Therefore, the larger polygon will have a perimeter of 30(15/12) = 37.5, or 38 to the justified number of significant digits stated.
The constant of proportionality or scale factor.
There is no formula for a rectangle. There are formula for calculating its area, perimeter or length of diagonals from its sides, or it is possible to calculate the length of one pair of sides given the other sides and the area or perimeter, or the two lots of sides given area and perimeter and so on.
Perimeter = (2 lengths) + (2 widths)1/2 of the perimeter = (length) + (width)Area = (length) x (width)So if you're given the area and the perimeter:-- Look for factor-pairs that multiply to give the area.-- The right pair of factors is the pair that add to give 1/2 of the perimeter.Example:Area = 24Perimeter = 22Factor pairs that make 24:1 x 242 x 123 x 84 x 6Which pair is it ?Perimeter = 221/2 the perimeter = 11.Look at the sums:1 + 24 = 252 + 12 = 143 + 8 = 11
Some people relate factor pairs to the sides of a rectangle. Length times width equals area; factor times factor equals product.
I think you are thinking of using the rectangles like you use Punnet squares. One side is multiplied times the other side and the product is put in the inside squares. This is handy when trying to factor expressions that are polynomials.
A rectangle has a perimeter of 28 inches. The length of one pair of sides is 8 inches per side. What is the length of each of the other sides? Six in.
CLS PRINT "PROGRAM: Calculate both perimeter/area of rectangle" PRINT INPUT " Length"; length INPUT "Breadth"; breadth PRINT PRINT "Perimeter: "; 2 * (length + breadth) PRINT " Area: "; length * breadth END
Its impossible to isolate both the length and width, but you can figure out the sum of one pair of length and width, which is 13.
One rectangle for each factor pair.
One rectangle per factor pair, six total.

Prime numbers have one factor pair, hence one rectangle.
