The length of one diagonal of rhombus is three times of another diagonal. If the area of field in the shape of rhombus is 96 cm2, then the length of long diagonal is

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.
