Calculate the length of the side of a rhombus, the perimeter of which is 19.6 cm.

We calculate the length of the side of the rhombus if it is known that the perimeter is 19.6 cm.

All sides of the rhombus are equal. The rhombus has 4 sides. To find the side of the rhombus, divide the perimeter of the rhombus by 4.

We get:

19.6 cm / 4 = 19.6 / 4 cm = (16 + 3.6) / 4 cm = 16/4 cm + 3.6 / 4 cm = 4 cm + 0.9 cm = 4.9 cm.

Hence we find that the side of the rhombus is 4.9 cm.
