Question

area of square field is 64 hectors find the cost of fencing it with the wire at 1.50 per meter is Rs.

Answer 1

FINAL ANWER:-

cost of fencing 64 hectors ⇒ ₹$4800$

GIVEN:-

• Area of square field is 64 hectors  (640000m2)

• Cost of fencing it with the wire at 1.50 per meter  

TO FIND:-

cost of fencing the square field land

FORMULA USED:-

$Perimeter\:of\:square=4*side\\Area\:of\:square=s^{2}$

SOLUTION:-

[ $1\: hector = 10000 m^{2}$ ]

It’s given that area of square field = 64 hectors (640000)

$Area\:of\:square=s^{2}\\640000=s^{2}\\s=\sqrt{640000}\\s=800 m$

∴ Length of square field is  

$Perimeter\:of\:square=4*side\\Perimeter\:of\:square=4*800\\Perimeter\:of\:square=3200m$  

∴ Cost to fencing 3200 meters of land  

$=1.50*3200$

⇒₹$4800$
