Solution

STEP 1 : Finding the area of floor of the room
Length of the room $= 6.5 m = 6.5 \times 100 = 650 c m$
Breadth of the room $= 5 m = 5 \times 100 = 500 c m$
Area of floor of the room $= 650 \times 500 = 3, 25, 000 m^{2}$
STEP 2 : Finding the number of square tiles required
Area of one tile of side 25 cm $= 25 \times 25 = 625 c m^{2}$
Number of square tiles required $= \frac{A r e a o f f l o o r o f t h e r o o m}{A r e a o f o n e t i l e}$
Number of square tiles required $= \frac{325000}{625} = 520$
STEP 3 : Finding the cost of flooring the room with the square tiles
Cost of flooring the room with square tile $= N u m b e r o f t i l e s \times C o s t o f o n e t i l e$
Cost of flooring the room with square tile $= 520 \times 4.70 = ₹ 2, 444$
Hence, the cost of flooring a room $6.5 m$ by $5 m$ with square tiles of side $25 c m$ is $₹ 2, 444$ .
