Question

How many tiles each 16 cm long and 10 cm vide will be required to pave a rectangular ourtyard 16 m long and 10 m wide?​

Answer 1

Step-by-step explanation:

Area of the room (Ar) = length × width

Ar = 15m × 10m = 180 m²

But 1 m² = 10000 cm²

160 m² = 160000cm²

Area of the square tile (As) = (length)² = l²

As = 16 cm × 10 cm = 160 cm²

Number of square tiles needed (n) = Ar/As

n = 160000/160 = 10000

Thus,

10000 square tiles will be needed to build the floor of a 16m x 10m room.

Answer 2

Answer:

Ans:-10000 tiles will be needed to pave the courtyard.

Step-by-step explanation:

Length of rectangular courtyard=16m=(16*100)cm=1600cm

Breadth of rectangular courtyard=10m=(10*100)cm=1000cm

Area of courtyard=Length*Breadth sq.units

                            =1600*1000sq.cm

Length of each tile=16cm

Breadth of each tile=10cm

Area of each tile=16*10 sq.cm

So, Number of tiles required to pave the courtyard=(1600*1000/16*10) tiles

                                                                                    =100*100 tiles

                                                                                    =10000 tiles

Ans:-10000 tiles will be needed to pave the courtyard.
