Answer:

Rs. 12500

Step-by-step explanation:

Perimeter of square: 4 × Sides

therefore, 4 × sides = 100m

side = 100/4

side = 25

Area of a square: Side²

as we know, it's side is 25m

area = 25²

= 25 × 25

= 625 meter²

as given in question, 1 m² = Rs.20

cost for 625m² is: (625 × 20)

= Rs. 12500
