There are infinitely many possible lengths for its sides. Select any number A, between 0 and 3 and let B = 6 - A
Then a parallelogram with opposite sides of A cm and B cm will have a perimeter of 12 cm.
Each of these parallelograms can come in infinite many shapes since the angle between the sides can vary infinitely.
Its perimeter is 48 centimeters (4X12=48).
The answer is 12 cm.
74 cm
12 cm
12 cm
If the short side is 6 then the opposite side must be the same, therefore 12 centimeters of the perimeter is the short sides leaving 14 centimeters for the long sides which would make them 7 centimeters each.
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.
The area is 9 cm212 / 4 = 33 * 3 = 9
4 root 9 ie 12 cm
Assuming the shape is a regular dodecagon, with 12 angles and lengths the same, a dodecagon with sides of 9.25 centimetres has a perimeter of 9.25 x 12 = 110 centimetres.
i its isosceles
A decagon has 10 equal sides, so if the perimeter is 120 cm each side must be 12 cm
