Question

The area of a square field is 2025 m square find the cost of fencing it at the cost of 15 rupees per metre

Answer 1

Step-by-step explanation:

• let side of square field be x
• so, area =x sq.
• x= √2025 = 45
• so, perimeter of square field=4a
• 4*45=180m
• cost of fencing the wall=180*15=2700Rs.

Answer 2

Answer: The cost of fencing at Rs15/m is Rs 2700.

Step-by-step explanation:

Since it is given in the question that the area of square field is 2025sq.m.

Area of square field = 2025sq.m.

Area of square field = side× side = 2025m²

⇒ side× side = 2025m²

⇒ side² = 2025m²

⇒ side = √2025m²

⇒ side = 45m

For fencing, it is necessary to find the perimeter of square field

Perimeter of square field = 4× sides = 4 × 45 = 180m.

Cost of fencing it at the cost of 15 rupees/metre = 180×15 = Rs2700

Hence, the cost of fencing at Rs15/m is Rs 2700.
