Answer:

Step-by-step explanation:

Required Area = 2(lb +bh+hl)-lb        {As the top of the swimming pool is open}

Required Area = 2(30x25 + 25x12 + 30x12) - 30x25

Required Area = 2(750 + 300 + 360) - 750

Required Area = 2 x 1410 - 750

Required Area = 2820 - 750

Required Area = 2070 m²

Total Cost = 2070 x 32

Total Cost = ₹66420
