A garden is 90m long and 75m broad.a path of 5m is to be built outside and around it.find the area of the path.also find the area of garden in hectare

Answer 1

total area of inner rectangle=90*75
                                 =6750m
area of  inner and outer rectangle=90+10=100;75+10=85
                                                     =100*85
                                                      =8500m²
area of path=area of  inner and outer rectangle-total area of inner rectangle
                   =8500-6750
=1750m²


area of garden in hectares=6750m²
                          =0.675 hectares²
