Question

A 350 cm long and300 cm broad floor is to be tiled with square tiles of side 10cm find the number of tiles also find the cost if each tile is worth rupees 35

Answer 1

The area of the floor = (350*300) cm^2

                                   = 10500 cm^2

The area of each tile = (10*10)

                                   = 100 cm^2

The number of tiles required=(10500/100) tiles

                                                = 105 tiles

The cost of tilling = rs. (105*35)

                             = rs. 3675

(Ans): The number of tiles is 105 and the cost of tilling is rs. 3675.

Answer 2

here is your

step by step explanation

no of tiles = (total area of the floor)÷(area of 1 tile)

so no of tiles = (350×300)÷10×10 = 350×30 = 1050

now total cost of tiles = 1050×35 = ₹36750
