Question

How to calculate the length of the side of a rhombus when the length of its diagonals is given?

Answer 1

Answer:

Let AC and BD intersect each other at O. Now, diagonals of rhombus bisect each other at right angles. Thus, we have.

Since AOB is a right angled triangle, by pythagoras theorem, we have.

Hence, AB = 13. Thus, length of each side of rhombus is 13 cm.
