Question

Pinky runs around a square field of side 85 m. Bob runs around a rectangular field with length 105 breaths 75m. Who covers more distance and by how much?

Answer 1

Answer:

Bob cover More by 31160

Step-by-step explanation:

1. 85×4=340
2. 105×2=210×75×2=150
3. 210×150=31500
4. 31500-340=31160

Answer 2

Step-by-step explanation:

➩ Answer :

• Bob covers more distance by 64 m.

➩ Question :

• Pinky runs around a square field of side 85 m. Bob runs around a rectangular field with length 105 breaths 75m. Who covers more distance and by how much?

➩ Solution :

Distance covered by Pinky in one round = Perimeter of square field

= 4 × length of a side of the square

= 4 × 85

= 340 m.

Distance covered by Bob in one round = Perimeter of the rectangular field

= 2(length + breadth)

= 2(130 + 172)

= 2 × 202

= 404 m.

∴ Difference in distance covered = 404 m - 340 m

= 404 - 340

= 64 m

Hence, Bob covers more distance by 64 m.
