Answer:
Area of road parralel to length =80×3=240
Area of road parralel to length =80×3=240Now,
Area of road parralel to length =80×3=240Now,Area of road parallel to breadth=60×3=180
Area of road parralel to length =80×3=240Now,Area of road parallel to breadth=60×3=180Total area will be=240+ 180-3*3( because they are intersecting and 3*3 is coming two times )
