Question

The area of the square park is 16,900 sq.m.Find the cost of fencing the park at the rate of ₹3.10 per meter

Answer 1

Area of square park= side²
16900 = side²
side =130 m
Perimeter of square= 4*side = 4*130 = 520 m
Cost of fencing= 520*3.10 =₹1612

Answer 2

Area of a square = Side * side = (Side)²

So, Side² = 16,900 m²

So, Side = √16,900 = 130 m

Perimeter of square = 4 * Side

                                  = 4 * 130 = 520 m

Rate of fencing = Rs. 3.10 per metre

So, cost = Rs. 3.10 * Perimeter = 3.10 * 520 = Rs. 1612

Answer : The cost of fencing the park would be Rs. 1612
