Explanation:

Step1: Recall perimeter formula

The perimeter \(P\) of a triangle is the sum of the lengths of its sides. So \(P = 33.5x+37.7x + 31.6x\).

Step2: Combine like - terms

\(33.5x+37.7x+31.6x=(33.5 + 37.7+31.6)x\).
Calculate \(33.5+37.7 + 31.6=102.8\). So \(P = 102.8x\).

Answer:

\(102.8x\)
