Question

path 2.5 metre wide is running around a square field whose side is 45 m find area of path

Answer 1

area of square field=45*45=2025
new length=45+(2.5*2)=45+5=50
breadth = 50
area = 50*50=2500
area of path = 2500-2025= 475 m^2

Answer 2

Area of field is is 2025m
Area of field including path is 45+2.5+2.5×45+2.5+2.5
That is 50×50 that is 2500m
Area of path is 2500-2025
So ans is 475m square
