Solution

The correct option is D 225 m
The pentagonal park has 5 equal sides.

Length of each side of the pentagonal track = 15 m

So, perimeter of the track is
= 15m × 5 = 75 m

Number of laps Ester runs along the track = 3

∴ Distance covered by Ester = Perimeter of the track × Number of laps

Substituting the values, we get:
Distance covered = 75m × 3 = 225 m

So, the total distance covered by Ester is 225 m.
