Answer:
no of tiles needed = 1000
total cost of tiling = ₹6,00,000 ( 6 lakh rupees)
Step-by-step explanation:
area of tiles = L× B = 12 × 10 = 120 cm²
area of region = l×b = 12m² = 120000cm²
therefore no of tiles needed =
area of region / area of tiles
= 120000/120
= 1000
1000 tiles are needed to fit the area completely
Rate of tiling = ₹5 / cm²
total cost of tiling = 5 × 120000
= 6,00,000
Answer:
Step-by-step explanation:
Tiles length= 12cm
Tiles breadth= 10cm
Area of one tiles= l×b= 12 × 10= 120cm sq.=
Rectangular region's length= 4m
rectangular region's breadth= 3m
Area of rectangular region= l×b= 4×3= 12m
Now,
1m = 100cm
1.20m= 120cm
No. of tiles that can fit= 12m/1.20m= 10 tiles
Cost of one tile= Rs.5
Cost of 10 tiles= 5×10= Rs.50
Therefore, 10 tiles can fit in the rectangular region at the rate of Rs. 50
