the answer is Rs11, 600.
explanation......
the area of park= L×B
= 100×65m = 6500m^2
then the area of one flower bed = 20×10m
=200m^2
so the area of six flower bed= 6×200m^2
=1200m^2
the area of park remains=6500-1200m^2
= 5300m^2
so the cost of laying the remaining portion=
= 20×5300m^2
= Rs11,600
please remark me.
