Krish runs a square park of side 65 m twice. Ritu runs around a rectangular park of
length 55m and breadth 25m thrice. Who covers less distance and by how much?
Answers
Step-by-step explanation:
In case of Krish :-
Side of square park = 65 m
Perimeter of square park = 4 × 65m
= 260m
Number of times Krish runs around the square park = 2
Therefore,
Total distance run by Krish = 2 × 260m
= 520 m
In case of Ritu :-
Length of the rectangular park = 55m
Breadth of the rectangle park = 25m
Perimeter of the rectangular park = 2×(55 + 25) m
= 2 × 80 m
= 160 m
Number of times Ritu runs around the rectangular park = 3
Therefore,
Total distance run by Ritu = 3 × 160m
= 480m
So, the distance run by Krish is more than Ritu (520 m > 480m) and by 40 m
