Question

Praveen runs around a square of side 40m. Naveen runs around a rectangle with length 43m and breadth 38m. Who covers more distance and by how much

Answer 1

Naveen covers more distance by 2 m

Answer 2

Praveen runs around a square of side= 40 m
Naveen runs around a rectangle of length = 43m and breadth = 38m

Perimeter of square = 4×sides
4×40= 160m
Perimeter of rectangle = 2(l+b)
=2×(43+38)= 2×81
=162m
so Naveen covers more distance by 2 meters
