Answer:
28
Step-by-step explanation:
The perimeter is calculated by adding all side lengths up.
So, to find the value of x, we can write the following equation:
6x + 3 + 4x + 2x + 1 = 5x + 5x + 3x + 2
- Add like terms on both sides of the equation.
12x + 4 = 13x + 2
- Transfer variables to one side and numbers to one side of the equation.
4 - 2 = 13x - 12x
2 = x
To find the perimeter, replace x with 2:
12×2 + 4 = 28
