Question

the length of a rectangular field is twice its breadth.meghana jogged around it 5 times and covered a dustance of 3 km. what is the length of the field?

Answer 1

Let the length of the rectangular field be 'x'm Then,according to the problem,breadth = x/2 m By the problem, 3000 m = 5*2(x+x/2) 3000=10((2x+x)/2) 3000=5(3x) 15x=3000 x=200 Therefore,the length of the rectangular field is 200m.

Answer 2

Let the breadth of rectangular field be x km
Length =2x km
Perimeter =2(l+b)=2(x+2x)=6x km.
According to the problem,
6x *5=3
30x=3
X=3/30
X=1/10
Breadth =1/10km=100m
Length =2/10km =1/5km=1/5*1000m =200m.

Ans :length is 200m
