Answer:
[tex]31\frac{1}{2}ft^2[/tex]
Step-by-step explanation:
From the information given each of the three rectangular countertops has dimension [tex]4\frac{3}{8}[/tex] by [tex]2\frac{2}{5}[/tex] feet.
The area of a rectangular shapes is the product of the dimensions.
Each rectangular countertop has area;
[tex]4\frac{3}{8}\times 2\frac{2}{5}=\frac{35}{8}\times \frac{12}{5} =10\frac{1}{2}ft^2[/tex]
Therefore the number of square feet tiles needed to cover all the countertops is [tex]=3\times 10\frac{1}{2}=31\frac{1}{2}ft^2[/tex]
