Question

the area of square plot is 4900 metres square find the length of rope which can go for time around the boundary of this plot

Answer 1

length is 70

since we know that the area of the square is 4 into side=4×70=280

Answer 2

given: area of a square plot=4900 m
side^2=4900
side=root 4900
side=70

so, perimeter= 4( side)
=4x70
=280 m

so length of rope which can go four times around the boundary
=4* perimeter
=4*280
=1120 metres

ans: 1120 m
