Question

a swimming pool measuring 4m by 300cm is to be converted by a rectangular tiles measuring 25cm by 8cm .find the number of tiles required?​

Answer 1

Answer:

Step-by-step explanation:

As we know: 1 meter = 100 cm.

4 m = 400 cm;

Total surface area = length * width = 400*300 = 120000 sq.cm;

Area of one tile is = 25*8 = 200 sq. cm;

Total no. of tiles required =  total surface area of pool / area of one tile;

Total no. of tiles required = 120000/200 = 600;

Answer 2

Answer:

The  number of tiles required = 600 tiles

Step-by-step explanation:

It is given that, a swimming pool measuring 4m by 300cm is to be converted by a rectangular tiles measuring 25cm by 8cm

To find the area of swimming pool

Area of rectangle = Length * Breadth

Here length = 4m = 400 cm

Breadth = 300 cm

Area = 400 * 300 = 120000 cm²

To find the area of one tile

Area = Length * Breadth

Here Length = 25 cm

Breadth = 8 cm

Area = 25 * 8 = 200 cm²

To find the number of tiles required

Number of tiles = Area of pool/Area of one tile = 120000/200 = 600

Therefore number of tiles required = 600 tiles
