Concept: Drawing the rhombus first will allow us to use the Pythagorean Theorem to determine the side length of the rhombus, which we will then multiply by 4 to obtain the perimeter.
To better comprehend it, let's first illustrate it.

We are aware that rhombus' diagonals cut each other at right angles.
AOB, BOC, COD, and DOA are all right-angled triangles as a result.
The diagonals are split because of O. AO = OC and DO = OB as a result.
These together with the diagonal lengths give us AO = OC = 5 cm and DO = OB = 12 cm.
As stated by the Pythagorean Theorem, "In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides."
Because AOB is a triangle with a right angle at O, it has a right angle. The Pythagorean Theorem will result in the following:
