Class 9th West Bengal Mathematics 15. Area and Perimeter of Triangle and Quadrilateral Shaped Region

Answer :

Given, The length of one diagonal of rhombus is three times of another diagonal and the area of field in the shape of rhombus is 96 cm².

Let diagonal one and two be D1 and D2 respectively.

Area of the rhombus = ×product of diagonals

(D₂)² = 64

D₂ =

D₂ = 8cm

Hence the longer diagonal D₁ = 3D₂

= 3×8

= 24cm.
