Marks: +1, -0

The area and the length of one of the diagonals of a rhombus is 54 cm2 and 9 cm respectively. Find the length of its other diagonal (in cm).

Solution:

Let length of one diagonal =

d

cm and length of other diagonal = 9 cm
⇒ Area of rhombus =

1/2 ×d_1d_2

⇒

1/2 ×9 × d = 54

⇒

d = {54×2}/9

⇒

d=12
