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= [tex]side^{2}[/tex]
Since we need to find if the side has the whole number, we can make the function to solve for side
side=[tex]\sqrt{area} }[/tex]
Then the side for each tile installer will be:
A= [tex]\sqrt{25 in^{2} }[/tex]= 5 inch
B= [tex]\sqrt{36 in^{2} }[/tex]= 6 inch
C= [tex]\sqrt{46 in^{2} }[/tex]= 6.78 inch
D= [tex]\sqrt{60 in^{2} }[/tex]= 7.74 inch
Both C and D have irrational sides
