Ahouse has 3 rectangular countertops. each countertop is 4 and 3/8 by 2 and 2/5 feet. how many square feet of tile is needed to cover all the countertops?

a. 8 3/20

b. 10 1/2

c. 24 9/20

d. 31 1/2

31\frac{1}{2}ft^2

Step-by-step explanation:

From the information given each of the three rectangular countertops has dimension 4\frac{3}{8} by  2\frac{2}{5} feet.

The area of a rectangular shapes is the product of the dimensions.

Each rectangular countertop has area;

4\frac{3}{8}\times 2\frac{2}{5}=\frac{35}{8}\times \frac{12}{5} =10\frac{1}{2}ft^2

Therefore the number of square feet tiles needed to cover all the countertops is D.

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope
