Find the length o

Answer :


The diagonals of a rhombus bisect each other at right angles.

Let the intersecting point be O.

So, we get right angled triangles.

We know that the Pythagoras Theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Let us consider ΔAOB.

By Pythagoras Theorem,

AB2 = AO2 + OB2

AB2 = 122 + 52

AB2 = 144 + 25

AB2 = 169

AB = 13cm

The length of side of the rhombus is 13cm.
