Answer:
Area of the rhombus is a rational number
Step-by-step explanation:
[tex]\frac{1}{2}[/tex] is a rational number.
The decimal expansion of a rational number is either terminating or non terminating and repeating.
[tex]d_{1}[/tex] is a terminating decimal and so it is a rational number.
[tex]d_{2}[/tex] is a repeating decimal and so it is also a rational number.
Therefore,
[tex]\frac{1}{2} d_{1} d_{2}[/tex] = product of three rational numbers
= a rational number
Hence, area of the rhombus is a rational number
