Let’s break down the problem step by step:

1. Triangle's Perimeter:

The perimeter of a triangle is the sum of its three side lengths. Based on the information given, let's denote the sides of the triangle as:

• $a$
• $b$
• $c$

Thus, the perimeter of the triangle is: $P_{\text{triangle}} = a + b + c$

2. Square's Perimeter:

The perimeter of a square is four times the length of one of its sides, since all sides are equal. If the side length of the square is $x$, then the perimeter of the square is: $P_{\text{square}} = 4x$

3. Perimeter Equality:

According to the problem, the perimeter of the triangle is equal to the perimeter of the square. Therefore, we can set up the equation: $a + b + c = 4x$

4. Solving for $x$:

At this point, I would need the actual side lengths of the triangle from the diagram to proceed with solving the equation. If you could provide those, I can plug them into the equation and find the value of $x$.

Feel free to upload the diagram or provide the missing side lengths, and I’ll continue from there.
