Length of the park$= 125\ m$

The breadth of the park$= 65\ m$

Area of the park$= l\times b$

$=125\ m\times65\ m=8125\ m^2$
 
Length of the park including path

$=125\ m+3\ m+3\ m=131\ m$

The breadth of the park including path

$= 65\ m+3\ m+3\ m=71\ m$

Area of the park including path

$131\ m\times71\ m=9301\ m^2$
 

Area of the path

$=9301\ m^2-8125\ m^2=1176\ m^2$

Hence the required area$= 1176\ m^2$
