Explanation:

Step1: Recall perimeter formula

Perimeter of a triangle is the sum of its three sides. So, \( P = a + b + c \), where \( a = 1\frac{3}{11} \), \( b = 2\frac{2}{11} \), \( c = 2\frac{4}{11} \).

Step2: Convert mixed numbers to improper fractions (or add directly)

Add the whole numbers and the fractions separately.
Whole numbers: \( 1 + 2 + 2 = 5 \)
Fractions: \( \frac{3}{11} + \frac{2}{11} + \frac{4}{11} = \frac{3 + 2 + 4}{11} = \frac{9}{11} \)

Step3: Combine whole and fraction

Combine the sum of whole numbers and sum of fractions: \( 5 + \frac{9}{11} = 5\frac{9}{11} \)

Answer:

\( 5\frac{9}{11} \)
