Question

find the cost of fencing a Square Garden whose each side is 20 metre at the rate of 15 rupees per metre​

Answer 1

Answer:

Rs. 1200

Step-by-step explanation:

Given: side = 20m

perimeter of a square= 4×side=4×20=80m

cost of fencing 1m = Rs.15

therefore, cost of fencing 80m = 15×80=Rs. 1200

Answer 2

Answer:

side = 20 m

so perimeter = 4× side

= 4 × 20 = 80cm

now, cost of 1 metre = 15 ₹

so, cost of 80 m = 15 × 80 = 1200₹
