Question

A mason has to fit a bathroom with square marble tiles of the largest possible in the



size of the bathroom is 10 by it. What would be the size in inches of the



that has to be cut and how many such tiles are required?

Answer 1

Find GCD of  10 and 8
It is 2.
1ft=12in, so 2ft=24in.
24 is the size (in inches),

To see how many are required,
8ft/24in
=8ft/2ft
=4
10ft/24in
10ft/2ft
=5
4×5=20
