If the diagonals of a rhombus are 18 cm and 24 cm respectively, then its side is equal to
Given,
ABCD is a rhombus
AC=24 cm, BD = 18 cm
= AB=BC=CD=DA [side of rhombus]
We know that diagonals of rhombus bisect each other at 90°
In right ∆ AOB
AB2 = BO2+AO2
AB2= 122+92 = 144+81 = 225
AB = 
Side of rhombus = 15 cm
