2

width of path,w=5 cm

Outer side of square =100+5+5=110 cm

Area of outer square =110

2

=12100 cm

2

Area of path =12100−10000=2100 cm

Area of garden including the path=

80m+5m=85m

Area=side×side=85×85=7225m²

Area of path= Area of garden including the path - area of garden

7225m²-(89×80)m

7225-6400

=825m²

So area of path is 825m²
