Answer 1

Answer:

cost of cementing its floors and walls at the rate of rs 14 per sq. m = 10920 ₹

Step-by-step explanation:

length of swimming pool is 30m

breadth of swimming pool is 10m

depth of swimming pool is 6m

Now Area of floor = 30 × 10 = 300 m²

Area of four walls = 2 ( 30 + 10 ) × 6 = 480 m²

So , total area to be cemented

= 300m² + 480 m²

= 780m²

Now cost of cementing 1m² = ₹14

hence, cost of cementing 780m² = ₹ 780 × 14 = 10920 ₹
