Question

4. The area of a square plot is 6400 m sq. Find the
length of wire which can go six times along
the boundary of the plot.​

Answer 1

Step-by-step explanation:

Area of the square plot = 6400 m²

Side of the square plot = √6400 m

= 80 m

Perimeter of the square plot = 4 × 80 m

= 320 m

Six times around the square = 6 × 320 m

= 1920 m

Length of the wire which can go six times along the boundary of the plot = 1920 m

= 1920/1000 km

= 1.920 km

Answer 2

Answer:

Step-by-step explanation:

area=6400

s^2=6400

s=√6400

s=8

perimeter =4s

=4*8

=32

According to the condition

length of the wore to fence it 6 times hence will be

32*6=192m
