I think
there there is a rectangle which has a length is 300 M and breadth is 200 m
perimeter of
a rectangle =2(l+b)
=2(300+200)
=2×500
=1000
then ,
the 10 M Wide Road is built-in three side of the plot and the 10 M Wide is road is built in the middle in a plot so,
we should - 40 m from 1000
=1000-40
= 960 metres
