(1) The length of the floor is three times the width.

Statement 1

The length of the floor is three times the width =>Length = 12m
Required number of square tile with side 0.25m = 48*16 ....Sufficient....BCE

Statement 1
The area of the floor is 48 square meters.
Floor is rectangular with width 4 m. Therefore length of the floor = 12m
Required number of square tile with side 0.25m = 48*16 ....Sufficient....A D

We need to calculate the area of the floor and divide by the area of each tile. The only information we need is the length of the floor.

(1) The length of the floor is three times the width. Sufficient--we can determine the length of the floor.
(2) The area of the floor is 48 square meters. Also sufficient--we can back-calculate the length of the floor.
