What is the cost of tiling a rectangular plot of length 600 long and 300 metre wide at the rate of rupees 7 per metre square

Answer»

Answer:

  • LENGTH = 600 metre
  • Breadth = 300 metre
  • Rate of tiling = Rs. 7 per metre square

• Area of the rectangular plot :

⇒ Area = Length × Breadth

⇒ Area = 600 m × 300 m

⇒ Area = 180000 m²

⠀⠀⠀⠀⠀───────────────

• COST of tiling the rectangular plot :

⇒ Cost = Area × Rate

⇒ Cost = 180000 m² × Rs. 7 per m²

⇒ Cost = 180000 × Rs. 7

⇒ Cost = Rs. 12,60,000

∴ Hence, cost of tiling is Rs. 12,60,000.
