Question

the area of a square field is 15625 metre square find the cost of wiring its boundary at the rate of the 17 per metre​

Answer 1

Step-by-step explanation:

area = 15625m²

area of square = s²

15625m² = s²

√15625 = s

125m = s

Now, the side of the field is 125m.

Perimeter of square = 4a (here a = side)

= 4*125

= 500m

Now cost,

1m = ₹17

500m = 500*17

500m = ₹8500

So, the cost of wiring it's boundary will be ₹8500.
