Question

8. A rectangular field is 120 m by 100 m. How many rounds of this field will a boy make if he covers
3300 metres?​

Answer 1

Answer:

Length = 120cm

Breadth = 100cm

Perimeter = 2(l+b)

= 2(120+100)

= 2 x 220

= 440cm

Length covered by the boy = 3300/440

= 7.5 rounds or

= 7 and 1/2 rounds

Answer 2

Answer:

Perimeter = 2(l+b)

= 2(120+100)

=2×220

=440 metres

Now,Rounds = Total distance/Perimeter

=3300/440

=30/4

=7.5 or 7 and 2/4 rounds.
