Q5 of 35 Page 73

Diagonals PR and QS of a rhombus PQRS are 20 cm and 48 cm respectively. Find the length of side PQ.

According to the properties of Rhombus diagonals of the rhombus bisects each other at 90°



In the rhombus PQRS


SO = OQ = 10 cm


PO= OR = 12cm


So in ΔPOQ


∠ POQ = 90°


⇒ PQ is hypotenuse


102 + 242 =PQ2


100 + 576 = PPQ2


676 = PQ2


26cm = PQ Ans
