Answer:
The area is rational because the numbers in the formula are rational.
Step-by-step explanation:
All repeating decimals are still rational because they can be expressed as fractions. For example,
[tex]$\frac{1}{7}=0.\overline{142857}$\end{document}[/tex]
So every recurring decimal must be a fraction.
Also every terminating decimal can be represented as a fraction.
0.25 = [tex]\frac{1}{4}[/tex]
So the area is rational because the numbers are rational.
Area = [tex]\frac{1}{2}[/tex] X Base X Height
Base is Rational and Height is Rational. Hence Area=Rational.
When these rational numbers are substituted into the formula,the area must be rational.
