Solution
The correct option is B 30ab km
Given perimeter = (120ab) km.
Let the side of the square-shaped farm be s km.
In a square, all sides are equal.
∴ s+s+s+s = Perimeter
⇒ 4s = 120ab
⇒ s = 30ab km
30ab km
Given perimeter = (120ab) km.
Let the side of the square-shaped farm be s km.
In a square, all sides are equal.
∴ s+s+s+s = Perimeter
⇒ 4s = 120ab
⇒ s = 30ab km
