Question

Riya runs around a square park of side 75 m, while Rima runs around a rectangular park with length 60 m and breadth 45 m. Who covers lesser distance and by how much?

• A. Rima, 90 m
• B. Riya, 90 m
• C. Rima, 100 m
• D. Riya, 80 m

Answer 1

The correct option is A Rima, 90 m

Total distance covered by Riya
= Perimeter of the square park

$=(4\times 75)$ m

$=300m$

Total distance covered by Rima
= Perimeter of the rectangular park

$=2(60+45)$m

$=(2\times 105)$ m

$=210m$

Difference = (300 - 210) m = 90 m

Rima covered less distance as compared to Riya by 90 metres.
