Answer:
So, let us consider the breadth as x
then, the breadth is 2x
now,
it is given that,
distance covered by gaurav is 900m in 15 rounds
so,
x(2x)(15)=900m
30x^2=900m
30x= √ 900
30x=30
x=30/30
Thus, x=1m
then, breadth of rectangle is 1m
and, length of rectangle is 1*2=2m

Given:-
- The length of the park is twice its breadth.
- The total distance covered by Gaurav is 900m.
To find:-
- Find the length and breadth of the park ?
Solutions:-
- Let the length of the park be 'l' m.
- Let the breadth of the park be 'b' m
We have,
The length of the park is twice its breadth.
=> l = 2b .......(i).
Gaurav takes 15 rounds of a rectangular park and the total distance covered by Gaurav is 900 m
=> 900/15
=> 60m
It means Gaurav cover 60 m distance in one round.
We know that,
The perimeter of the rectangular park => 2(l + b)
According to question:-
=> 60 = 2(l + b)
=> 60 = 2(2b + b) (From equation 1)
=> 60 = 2(3b)
=> 60 = 6b
=> 60/6 = b
=> 10 = b
=> b = 10m
Putting the value of 'b' in equation (i).
=> l = 2b
=> l = 2 × 10
=> l = 20m
Hence, the length and breadth of the rectangular park is 20m and 10m.
