Answer 1

Answer:

Step-by-step explanation:

Given 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?

The number of tiles will be minimum if size of each marble is maximum.

Size of each tile will be hcf of 4.55 and 5.25 m

We need to find the hcf of 455 and 525 so the factors are

455 = 5 x 7 x 13

525 = 5 x 5 x 3 x 7

So hcf is 5 x 7 = 35

Now hcf is 0.35

Therefore largest size of tile used will be 0.35 m
