The ratio of the perimeters is equal to the scale factor. If rectangle #1 has sides L and W, then the perimeter is 2*L1 + 2*W1 = 2*(L1 + W1).
If rectangle # 2 is similar to #1 and sides are scaled by a factor S, so that L2 = S*L1 and W2 = S*W1, the perimeter of rectangle #2 is 2*(L2 + W2)= 2*(S*L1 + S*W1) = S*2*(L1 + W1) = S*(perimeter of rectangle #1).

If Polygons abcd is similar to efgh are similar find the length of ab?
It is k times the perimeter of eh where k is the constant ratio of the sides of abcd to the corresponding sides of efgh.

Find the perimetre of rectangle with length 70mm and width 25mm?
I don't understand why there are so many questions about rectangles' perimeter. You just add the length and the width and double your answer....

Polygons abcd and afge are similar ad equals 12 and ad equals 12 if af equals 6 if the perimeter of afge is 28 what is the perimeter of abcd?
56 (: When we say polygon abcd is similar to polygon afge, they already told you which are the lines that are similar. ab:af=bc:fg=cd:ge etc. Lines ad and af are not similar in length and therefore cannot be used to find perimeter of polygon abcd even though the perimeter of polygon afge is given.
