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
