Question

The area of a square field is 49,28A m². Find
the cost of fencing the field at 215 per metre​

Answer 1

$</p><p>\huge\red{\boxed{\bold{Explanation :}}}$

area of square = a × a , where a is edge length

area of square = 49284 m^2 = a^2

therefore, a = √(49284 m^2) = 222 m

length of fence = perimeter of square

= 4 × a = 222 × 4 m = 888 m

now, cost of fencing = ₹(888 × 215) = ₹1,90,920

Answer 2

Step-by-step explanation:

area of square = a × a , where a is edge length

area of square = 49284 m^2 = a^2

therefore, a = √(49284 m^2) = 222 m

length of fence = perimeter of square

= 4 × a = 222 × 4 m = 888 m

now, cost of fencing = ₹(888 × 215) = ₹1,90,920
