Answer:
The area of triangle expressed as a monomial is [tex]27x^{2}[/tex]
Step-by-step explanation:
we know that
The area of a triangle is equal to
[tex]A=\frac{1}{2}bh[/tex]
In this problem we have
[tex]h=9x\ units[/tex]
[tex]b=6x\ units[/tex]
substitute
[tex]A=\frac{1}{2}(6x)(9x)=27x^{2}\ units^{2}[/tex]
