Question

A tile installer has selected four different size square tiles to cover a floor. The areas of the tiles are:

Answer 1

Answer:

C and D

Step-by-step explanation:

The length of the sides will be irrational if it is not a whole number. The tile installer has a square shape, so the formula for area is

area= $side^{2}$

Since we need to find if the side has the whole number, we can make the function to solve for side

side=$\sqrt{area} }$

Then the side for each tile installer will be:

A= $\sqrt{25 in^{2} }$= 5 inch

B= $\sqrt{36 in^{2} }$= 6 inch

C= $\sqrt{46 in^{2} }$= 6.78 inch

D= $\sqrt{60 in^{2} }$= 7.74 inch

Both C and D have irrational sides
