Expert Answer
Let ABCD be the rhombus. Diagonal AC = 24 cm and BD = 18 cm.
Diagonals of a rhombus bisect each other at right angles.
AO = OC = 12 cm and OB = OD = 9 cm and 
AOD = 90oIn right 
AOD, AO = 12 cm and OD = 9 cm
AOD, AO = 12 cm and OD = 9 cmBy Pythagoras theorem, AD2 = AO2 + OD2
AD2 = (12)2 + (9)2 AD = 15 cmAll sides of a rhombus are equal.
Hence, each side of the rhombus = 15 cm
