Let 1st path ABCD and second path PQRS
Area of path ABCD=80*4=320m^2
Area of path PQRS=60*4=240m^2
Area of center square =4*4=16m^2
Area of path =320+240-16=544m^2
Area of path ABCD=80*4=320m^2
Area of path PQRS=60*4=240m^2
Area of center square =4*4=16m^2
Area of path =320+240-16=544m^2

length of the plot = 80mq.
breath of the plot = 60msq.
area of the plot =l×b
80×60msq.=4800msq.
area of the plot =4800×4=19200
hence the total area used as path is 19200
