Answer 1

Answer:

The number of tiles required are 800.

Step-by-step explanation:

Consider the provided information.

The length and breadth of the rectangular room is 520cm and 140cm respectively.

Find the are using the formula:

Area of rectangle = Length × Breadth

                             = 520 × 140

                             = 72800

Hence, the area of the rectangular room is 72800 cm².

Now, calculate the area of a tile as shown:

Area of a tile = 13 × 7 = 91

The area of a tile is 91 cm².

Now, to find the number of tiles divide the area of rectangular room by area of the tile.

72800/91 = 800

Hence, the number of tiles required are 800.
