A rectangular courtyard 4.55 meters long and 5.25 meters wide is paved exactly…

Correct Option: (d)

Here, we are asked to find the largest size of tile. Therefore, calculate H.C.F.

Step 1: Covert numbers without decimal places i.e 455 cm and 525 cm

Step 2: Find the H.C.F. of 455 and 525

H.C.F. of 455 and 525 = 35 cm

Hence, the largest size of the tile is 35 cm.
