Question

A rectangular lawn measuring 50m by 36m is surrounded externally by a path which is 2m wide . Find the area of the path. Also calculate the cost of levelling of the path at ruppess 16 per m square

Answer 1

Gn,
   length(l) of lawn = 50m
   breadth(b)of lawn = 36m
   width of path = 2m
   so the,
     length(L) of outer rectangle = 50+2+2 = 54m
     breadth(B) of outer rectangle = 36+2+2 = 40m
                   
                  Area of path = Area of outer rectangle - Area of inner lawn
                                       = L×B - l×b
                                       = 54×40 - 50×36
                                       = 2160 - 1800
                                       =360m^2
                 Cost of levelling path = 360×16
                                                   =Rs 5760
