credits - @topper Length of rectangular garden =80m
and breadth =40m
Width of crossing path 2.5m
So,
Area of length wise path =80×2.5=200m
2
and
Area of breadth wise path =40×2.5=100m
2
(i) Total area of both paths
=200+100−2.5×2.5m
2
=300−6.25=293.75m
2
(ii) Area of unshaded portion
= Area of garden − Area of paths
=80×40−293.75m
2
=3200−293.75m
2
=2906.25m
