This question cannot be answered because:
74 cm
The answer is 12 cm.
The area is 9 cm212 / 4 = 33 * 3 = 9
The sidelength of a square is the square root of its area, and its perimeter is four time this. 4 x sqrt(9 cm2) = 12 centimetres.
A decagon has 10 equal sides, so if the perimeter is 120 cm each side must be 12 cm

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.
74 cm
Its perimeter is 48 centimeters (4X12=48).
The answer is 12 cm.
If abcd is a parallelogram, then the lengths ab and ad are sufficient. The perimeter is 36 units.
12 in.
A+=14 * * * * * Not sure what the above answer means. But whatever it is, it is not the correct answer to this question! ae is half of ad so the second figure has the linear dimensions of the second are half that of the first. Therefore, the perimeter is half ie 27 units.

The perimeter of a square with a diagonal of 12 centimeters is: 33.9 centimeters.In future, to find out the perimeter of a square when you only know it's diagonal, use Pythagoras or times the diagonal by 2.828427125.This number is irrational, and is like a pi for the diagonals of squares.I call it Tau.It is the relationship between the diagonal of all squares and there perimeter.
4 root 9 ie 12 cm
