Answer 1

Answer:

When one round is made total distance the boy covers =2(120+100)

=440m

Given that boy has covered 2200 m , thus the must have made (2200/440)

rounds that means 5 full rounds.

Step-by-step explanation:

hope it's help full

Answer 2

7th solution:)--

Length of the rectangle =120m

Breadth of the rectangle =100m

∴ perimeter of the rectangle =2(1+b)

=2(120+100)

=2(220)

=440m

Now, the total distance covered =2200m

If he covers 440m in one round

Total number of rounds he will cover

=total distance / perimeter

= 2200/ 440

= 5

∴ Thus, he will cover the distance in five rounds....
