Answer: Option E

Solution(By Examveda Team)

$$\eqalign{ & {\text{Breadth}} = \frac{{{\text{Area}}}}{{{\text{Length}}}} \cr & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = \left( {\frac{{2100}}{{60}}} \right)m \cr & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = 35m \cr & \therefore {\text{Perimeter}} = 2\left( {60 + 35} \right)m \cr & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = 190\,m \cr} $$
