Let d¹ and d²  be the diagonals of the given rhombus.

Then, d1=24 cm and d2=?

Now,Given: Area of rhombus =216 cm2

⇒1/2×d¹×d²=216

⇒1/2×24×d²=216

⇒d²=216×2×241

⇒d²=18

∴ Length of second diagonal =d²=18 cm

Answer 2

Answer:

Let d¹ and d² be the diagonals of the given rhombus.

Then, d1=24 cm and d2=?

Now,Given: Area of rhombus =216 cm2

⇒1/2×d¹×d²=216

⇒1/2×24×d²=216

⇒d²=216×2×241

⇒d²=18

∴ Length of second diagonal =d²=18 cm
