Find the least number of square tiles for a terrace of 6.75 mts. long and 5.40 mts. breadth.

A) 20
B) 45
C) 135
D) None of these

Correct Answer:

A) 20

Description for Correct answer:
HCF of 675 and 540 gives each side of a tile. Which is 135 cm.

\( \Large \frac{675}{540},\ \frac{135}{45} = 0 \)

Therefore, Number of tiles =\( \Large \frac{675 \times 540}{135 \times 135} \)

= \( \Large 5 \times 4 = 20 \)
