3600 sq. m
100*100-80*80 =(100+80)(100-80)=3600
100*100-80*80 =(100+80)(100-80)=3600

It is a Square so All sides are 100 m.
But it has a 10m path all around it inside..so two parallel sides have 80 m length..20m less 10+10.(Dimension of path..
Calculations:
Area of square= (100)^2 = 10,000sq m
Area of Square( formed inside) = (80)^2 = 6,400
》10,000-6,400 = 3,600 sq m
