Question

The area of rhombus is 120 cm

and one of the diagonals is 8 cm. Find the other

diagonal​

Answer 1

30

Step-by-step explanation:

Area of Rhombus = 1/2 × d1 ×d2 = 120 cm

D1 = 8 cm

So ,

Area = 1/2 × 8 × d2

120 cm = 4× d2

d2 = 120 / 4

= 30 Ans ☑️☑️☑️

Answer 2

Area of a rhombus= 1/2 ×product of its diagonals

Area of a rhombus= 1/2×d1×d2

⇒120= 1/2 × 8 ×d2

⇒ 8d2 =120×2

d2 =240/8

d2=30 cm

∴ the other diagonal is 30 cm.
