A $3\ m$ wide path runs outside and around a rectangular park of length $125\ m$ and breadth $65\ m$. Find the area of the path.
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$= 1176\ m^2$
