Question

Rohit jogs twice around a rectangular park of length 24. 5 m and breadth 14.6 m. Rakeshjogs thrice around another rectangular park of length 15.5m and breadth 11.4m. who runs longer and by how much?​

Answer 1

Rohit jogs run rectangular park

l=24.5m

b=11.4m

• THE PERIMETER OF A RECTANGULAR IS 2(l ➕b) THE PERIMETER OF A RECTANGULAR IS 2(l ➕b)

so 2xl plus b

2 x 24.5 ➕ 11.4=

60.4 m

he run twice so 60.4^2

=60.4x60.4=3648.16

RAKESH jogs runs the rectangular ground thrice

l= 15.5m

b=11.4m

THE PERIMETER OF A RECTANGULAR IS 2(l ➕b)

2x15.5➕ 11.4

=42.4

he runs thrice a ground

so 42.4^3

42.4x42.4x42.4

=76225.024

SO RAKESH JOGS RUN LONGER THAN ROHITH JOGS.
