here's ur answer frnd...
given length and breadth of the rectangular ground is 90m and 33m
area of the rectangular ground=l×b
=90×32
=2880m²
area covered by the circular tank=πr²
=22/7×14×14
=22×2×14
=616m²
remaining area of the ground=2880-616
=2264m²
total cost of planting grass in the remaining area if per m² costs $2.50=2264×2.50
=$5660
