Answer:
Step-by-step explanation:
On saturday the distance covered by her per round is perimeter of park = 2(l+b)= 2(400+200)= 1200m per round.
But as she took 5 rounds the total distance is 5×1200=6000m.
On sunday the distance covered by her per round is perimeter =2(l+b)= 2(150+450)= 1200m. As she took 6 rounds the total distance on sunday is 6×1200=7200m. So she travelled more on sunday
