Question

Perimeter of a triangle. The perimeter of the triangle
shown in the accompanying figure is 12 meters. Determine
the values of x, x + 1, and x + 2 by solving the equation
x + (x + 1) + (x + 2) = 12.
x + (x + 1) + (x + 2) = 12

3x + 3 = 12
3x = 9
x = 3

3 + 1 = 4
3 + 2 = 5


idk how to do this
12 meters but i still don't get this
