Question

find the cost of putting a wire along the boundary of a square field of area 625hectare , if wire costs ₹15per m.( hint : 1 hectare= 10000 m²​

Answer 1

❀ Your Answer Is ₹15000.

ExplanaTion:-

Given:-

• Area of the square field = 625 hectares.

• 1 hectare = 10000 m².

• Cost of fencing the wire = ₹15 per meter.

To Find:-

• The total cost of fencing.

Formulas Used:-

↦ Area of square = Side.

↦ Perimeter of square = 4 × Side.

Let the side of the field be S.

So Here,

↦ Area of the field = 625 hectares.

↦ S × S = (625 × 10000) m².

↦ S² = 6250000 m².

↦ S = √6250000 m².

↦ S = 2,500 m.

❀ Therefore the side of the field is 2,500 meters.

Now,

↦ Perimeter of the field = 4 × Side.

= 4 × 2,500 m.

= 1000 m.

Also,

❀ Cost of fencing one meter = ₹15.

So cost of fencing 1000 m:-

= ₹ 15 × 1000 m.

= ₹ 15000.

❝So the total cost of fencing the field is ₹ 15000.❞

Answer 2

Answer:

answer is 150000

Step-by-step explanation:

area =625 hectare

be a be side

=>a×a=(625×10000)m²

=>a²=6250000m²

=>a=√6250000

=>a=2500m²

side=2500

now, perimeter=4×2500

=10000m

cost=15×10000

=150000

#answer=150000
