Question

Rohan makes 8 full rounds of a rectangular field length a 120m and breadth 90m. Some school boys run along the boundary of the playground and makes 15 complete round in 45mins . How much distance did they run during this period.

Answer 1

Step-by-step explanation:

Here distance covered by school boys= perimeter of the field × no. of rounds completed

= 2(120m+90m)× 15

= 2× 210m× 15

= 6300m or 6.3km

Answer 2

1.420×8=3360m

2.420×15=6300m
