Pinky runs twice around a square field of side 75m, Bob runs around a rectangular field of length 160m and breadth 150m. Who covers more distance and by how much?
Answers
Answer:
Bob covers for distance than Pinky by 20m
Step-by-step explanation:
length of the side of square field runs by Pinky=75m
It's perimeter=4s=4×75=300
distance covers by Pinky=2×300
=600m
length of rectangular field run by Bob=160m
breath of rectangular field=150m
perimeter=2(l+b)
=2(160+150)
=2×310
=620m
So,Bob covers more distance than Pinky by 20m
Step-by-step explanation:
Pinky runs twice a square field with length 75m
perimeter =75×4
=300
as she ran twice = 300×2=600
Bob runs around a rectangular field with length 160m and breadth 150m
perimeter = 2×(160+150)
=2×210=420
600m is greater so pinky ran more.
she ran much by=600-420
=180
she ran more by 180 m
