A courtyard 4.55 m long and 5.25 m broad is paved with square tiles of equal size. What is the largest size of tile used?

• A. 21 cm
• B. 28 cm
• C. 35 cm
• D. 25 cm

Answer 1

Answer:

C. 35 cm

1m = 100cm, 4.55 m = 455 cm, 5.25 m = 525 cm,

Find HCF of 455 and 525, 455 =5 x 7 x 13, 525= $5 ^ 2 \times 3\times 7$

HCF=5 x 7=35 cm
