Question

Around a large park of length 300 metres and breadth 200 metres, there is a track of width 2 metres, for the persons to take morning and evening walks. Find the area of this track.

Answer 1

length of the park = 300m

breadth of the park = 200m

area of the park = 300m*200m
=60000m^2

length of the park including track = l+2w
=300+2(2)
=300+4=304m

breadth of the park including track = b+2w
=200+2(2)
=200+4=204

area of the park including track = 304*204=62016

area of the track = area of the park including track - area of the park

=62016-60000=2016m^2
