Question

A piece on and is in the shape of a square and its area
1000 m - us has to be fenced using wire. The barbed we
is available only in integral lengths. What is the minimum lengan
of the barbed wire that has to be bought for this purpose​

Answer 1

Answer:

127m

Step-by-step explanation:

Since area of square = 1000m²

side = √ area = √1000

= 10√10 m

= 31.6 m ( approx)

perimeter = 31.6×4

=126.4m

since wire can only be bought in integral values , least length that can be bought is 127m

Answer 2

Answer:

A square of area 1000m^2 has a side sqrt(1000) m ...about 31.62m

The length of fence needed = 4*31.62m =126.48m

To leave a little spare, and because the wire is sold in unit lengths, buy 127m.
