Given:

Area of the rectangular field = 3600 m 2

Length (L) = 45 m

Formula used:

Area = Length × Width

Perimeter = 2 × (Length + Width)

Calculation:

3600 = 45 × Width

⇒ Width = 3600 / 45

⇒ Width = 80 m

Perimeter = 2 × (45 + 80)

⇒ Perimeter = 2 × 125

⇒ Perimeter = 250 m

∴ The correct answer is option 4.
