Option 1 : 40 cm and 60 cm

**GIVEN:**

Diagonal of a rhombus are in the ratio of 2 : 3

The area of the rhombus is 1200 m2

**FORMULA USED:**

Area of rhombus = 1/2 × d1 × d2

where d1 and d2 are diagonal of the rhombus

**CALCULATION:**

Let the diagonal of the rhombus be 2x and 3x respectively

Area of rhombus = 1/2 × 2x × 3x

⇒ 1200 = 1/2 × 2x × 3x

⇒ x^{2} = 400

⇒ x = 20 cm

∴ **diagonal of rhombus = 2 × 20 = 40 cm and 3 × 20 = 60 cm**
