Question

Pinky runs around a square field of side 75 cm bubbles around a rectangular field with length 16 cm and breadth 105 m who covers more distance and by how much ?

Answer 1

distance ran by Pinky = 75×4

= 300 cm

distance run by Bubbles = 2(16+10500)=32+21000= 21032 cm

Bubbles run more and 21032-300 cms

Answer 2

Step-by-step explanation:

Length of side of the square ( a )= 75cm

Distance covered by pinky = perimeter of the square field

Perimeter of the square field = 4a units

= 4× 75

=300 cm

Distance covered by pinky= 300cm

Length of the rectangular field (l)= 16 cm

Breadth of the rectangular field (b)=105cm

Distance covered by bubbles = perimeter of the rectangular field

Perimeter of the rectangular field = 2 (l + b ) units

= 2× (16 + 105)

= 2 × 121

= 242 cm

Distance covered by bubbles= 242 cm

Therefore pinky covered .more distance than bubbles by 58cm.
