Final answer:
The value of x is 0.625 for the square and 6 for the equilateral triangle.
Step-by-step explanation:
To find the value of x, we need to set up equations using the given information. Let's start with the perimeter of the square, which is 2.5x. The perimeter of a square is found by multiplying the length of one side by 4. So, we have 4 * x = 2.5x. Solving this equation, we get x = 0.625.
Next, let's look at the perimeter of the equilateral triangle, which is 1.5x + 6. The perimeter of an equilateral triangle is found by multiplying the length of one side by 3. So, we have 3 * x = 1.5x + 6. Solving this equation, we get x = 6.
Therefore, the value of x is 0.625 for the square and 6 for the equilateral triangle.
