Question

The area of a square field is 422500 sq metre .How much string is required for fixing along the sides as a fence .​

Answer 1

Step-by-step explanation:

Equation for area is +A+=+s%5E2+

Equation for perimeter is +P+=+4s+

where +s+ is the length of a side

given:

+A+=+422500+ m2

+422500+=+s%5E2+

+s+=+sqrt%28+422500+%29+

+s+=+650+ m

and

+P+=+4%2A650+

+P+=+2600+ m

2,600 meters of string is needed

Answer 2

Step-by-step explanation:

We are given the area we have to find the perimeter now so

ATQ

422500=side*side

side^2=422500

√422500= side

side=650

Now we need to find perimeter of the field

perimeter of square is 4*side

650*4=2600

so we need 2600 meters of string
