Option 2 : 24 m

**Given: **

Area of rectangle = 480 m2

Length ∶ Breadth = 6 ∶ 5

**Formula Used:**

Area of rectangle = Length × Breadth

**Calculation:**

Let the length of the rectangle is 6x

The breadth of rectangle = 5x

Area of rectangle = Length × Breadth

⇒ 480 = 6x × 5x

⇒ x^{2} = 16

⇒ x = 4

⇒ Length = 6x = 6 × 4 = 24 m

**∴ Length of rectangle is 24 m**
