a rectangular hall is measured 219 by 210 how long will it take for a boy to take to round around the horse if the work at the rate of 2.5 metre second
Answers
Given :-----
- Length of rectangular hall = 219m
- Breadth of rectangular hall = 210m
- Speed of horse = 2.5m/sec.
To Find :-----
- Time taken by boy in horse , around the rectangular hall ?
Solution :------
The boy will cover distance Equal to Perimeter of rectangular hall in one round .
→ Perimeter of Rectangle = 2(length + Breadth)
Putting values we get,
→ Perimeter of Rectangular hall = 2(219+210) = 858m
__________________________________
Now, speed of horse is = 2.5m/sec.
and the boy has to cover = 858 m distance ,
Now, we know that,
→ Time = Distance /speed
Putting values again,
→ Time = 858/2.5 = 343.2 seconds .
__________________________________
Now, we know that ,
→ 60 seconds = 1 minutes
→ 300 seconds = 5 minutes .
So, the boy will take 5 minutes 23.2 seconds to cover around the rectangular hall ...

• Length of rectangle hall= 219 m
• Breadth of rectangle hall= 210 m
• Speed of horse= 2.5 m/s
• Time to cover the distance.
We know that perimeter of rectangle= 2(length+breadth)
Perimeter of rectangular hall:-
=2(219+210)
=
Now,
speed of horse is 2.5 m/s
Distance is 858 m
As we know ,
•°• The boy takes 343.25 s to take round around the rectangular hall.
