PQRS is a rhombus. The diagonals are PQ & RS.
PQ = 30 cms RS = 16 cms
According to fig In Rhombus the diagonals bisect
Each other.
∴ PQ & RS bisect at O.
PO = OQ
SO = OR
Considering the ∆ POR
PR2 = PO2 + OR2
= 152 + 82
= 225 + 64 = 289
∴ PR = \(\sqrt{289}\) = 17cms
∴ The perimeter of the rhombus = 4 × side PR
= 4 × 17 = 68 cms
