Answer 1

1500 square tiles are required. The total cost required is 3750 rupees.

Step-by-step explanation:

Consider the provided information.

The length of the square tile is 12 cm.

Area of square is: $A=(side)^2$

The area cover by one tile is: $A=(12)^2=144$

The area cover by one tile is 144 cm².

The dimension of wall is 7.2m × 3m

1 m = 100 cm

Therefore, 7.2 m = 720 cm, 3 m = 300 cm.

The area of wall is: $A=720\times300=216000$

Thus, the area of wall is 216000 cm².

Number of tiles required = $\frac{216000}{144 } =1500$

Therefore, 1500 square tiles are required.

The cost of each tile is 2.50 rupees.

Thus, the cost of 1500 tiles are: 1500 × 2.50 = 3750 rupees

Hence, the total cost required is 3750 rupees.
