Question

saloni runs around a square park of side 85m whereas roja runs a triangular park of each side 90.5m.who covers less distance

Answer 1

Saloni runs around a square park where each side =85m
so the total distance covered=85×4=340m
and Roja runs around a triangular park of side 90.5 each
the distance coveres=90.5×3=271.5m

so Roja covers less distance.


hope it helps:)

please mark as brainliest..please

Answer 2

Side =85
Therefore. Perimetre =4×side
=4×85
= 340
And
Side of triangle =90.5
Perimeter =sum of all three side of triangle =3×90.5=271.5
Hence
Sonali runs less
