• A. $12$ sq units
• B. $15$ sq units
• C. $10$ sq units
• D. $5$ sq units

Answer 1

The correct option is B $15$ sq units

Number of rows in the rectangle $=3$
Number of tiles in each row $=5$
Total number of tiles $=$ rows $\times$ number of tiles in each row $=3\times 5=15$


Area of each tile $=1$ sq unit.
Area of $15$ tiles $=15\times 1=15$ sq units
Therefore area of floor is $15$ sq units.
