Question

Prem runs around a square park of side 80 m. Sunil runs around a rectangular park having length 65 mand
width 55 m. Who runs a greater distance?​

Answer 1

Answer:

perimetre of square =s×4=s×80 =320m.

perimetre of rectangle=2×(l+b)

=2×(65+55)=2×(120)=240m.

So,prem runs more distance than Sunil.

Answer 2

Answer :

___________________________

Prem runs around square park having sides = 80 cm

So , distance covered by him

= Primeter of the square park

= 80 × 4

= 320 m

Sunil runs around a rectangular park having sides => length = 65 m and breadth = 55 m

So, the distance covered by him

= Perimeter of the rectangular park

= 2 ( l + b )

= 2 × ( 65 + 55 )

= 2 × 120

= 240 m

320 m > 240 m

So, Prem runs greater than Sunil.
