The perimeter of triangle is [tex]7\frac{1}{3}[/tex] units.
Step-by-step explanation:
Given sides of triangle are;
[tex]1\frac{5}{12},2\frac{2}{3}, \ and\ 3\frac{1}{4}[/tex]
Writing in simple fraction form;
[tex]\frac{17}{12},\frac{8}{3}, and \frac{13}{4}[/tex]
Perimeter = Sum of all sides
Perimeter = [tex]\frac{17}{12}+\frac{8}{3}+\frac{13}{4}[/tex]
Perimeter = [tex]\frac{17+32+39}{12}=\frac{88}{12}[/tex]
Perimeter = [tex]\frac{22}{3}=7\frac{1}{3}[/tex]
The perimeter of triangle is [tex]7\frac{1}{3}[/tex] units.
