Question

a rectangular lawn measuring 50m by 36m is surrounded externally by a path which is 2m wide. find the area of path​

Answer 1

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 = 360×3.25

=Rs.1170
