Question

pinky runs around a square field of side 75 m bob runs around a rectangular field with length 160m and breadth 105m who cover more distance and by how much

Answer 1

Distance covered by Pinky= Perimeter of Square feild

: : Distance covered by Pinky= 4×Side

=4× 75m

=300 m

Distance covered by Bob= Perimeter of Rectangular feild

: : Distance covered by Bob= 2×(l+b)

=2×(160+105)

=2×265

= 530m

Since 530m>300m, Bob ran more.

Bob ran more by= 530m-300m=230m.

Answer) Bob ran more by 230 m.

Answer 2

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

Distance covered by Pinky in one round = 4 × length of a side

Distance covered by Pinky in one round = 4 × 75 m

Distance covered by Pinky in one round = 300 m

_____________________

Distance covered by Bob in one round = Perimeter of the rectangle

Distance covered by Bob in one round = 2 × (length + breadth)

Distance covered by Bob in one round = 2 × (160 m + 105 m)

Distance covered by Bob in one round = 2 × 265 m

Distance covered by Bob in one round = 530 m

____________________

Difference in the distance covered = 530m - 300m

Difference in the distance covered = 230 m

Therefore:-

• Bob covers more distance by 230 m.
