Answer:

the perimeter of the triangle is 13
in^(2)

Explanation:

All you have to do is add up all the sides together, but first we need to find a common denominator, and it can be 12

3(1)/(3) =
(10)/(3) = (40)/(12) ( i multiplied them by 4 (numerator and denominator))

4(1)/(6) = (25)/(6) = (50)/(12) ( i multiplied them by 2 (numerator and denominator))

5(1)/(2) = (11)/(2) = (66)/(12) ( i multiplied them by 6 (numerator and denominator))

Now that you have a common denominator for all 3 fractions, you can now add them all up

(40)/(12) + (50)/(12) + (66)/(12)

Now to add, the denominator has to stay the same (12), and add up all the numerators

(40)/(12) + (50)/(12) = (90)/(12) + (66)/(12) = (156)/(12) = 13 (simplified)

Hope this helped!
