Answer:
The base of the triangle is [tex]6\ mm[/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]A=33\ mm^{2}[/tex]
[tex]h=11\ mm[/tex]
substitute and solve for b
[tex]33=\frac{1}{2}b(11)[/tex]
[tex]b=33*2/11=6\ mm[/tex]
