Answer:
[tex]\frac{20}{9}[/tex] square feet
Step-by-step explanation:
We are given that
Side of square tile=[tex]\frac{1}{3} foot[/tex]
Total number of tiles used in rectangular floor=20
Area of square=[tex](Side)^2[/tex]
Area of square tile=[tex](\frac{1}{3})^2=\frac{1}{9}[/tex]square feet
Area of rectangular floor covered by square tiles =Area of 20 square tiles
Area of rectangular floor covered by square tiles=[tex]20\times \frac{1}{9}[/tex] square feet
Area of rectangular floor covered by square tiles=[tex]\frac{20}{9}[/tex] square feet
Hence, the area of rectangular floor covered by square tiles=[tex]\frac{20}{9}[/tex] square feet
