The definition of congruent is that the sides are the same length or otherwise identical. This means that
. From this, we can solve for x.
Subtract 18 from both sides.
Subtract 3x from both sides.
This means x is equal to 3.
The perimeter of a shape is the length of all sides added together. So the equation should be
. Since we know the value of x, we can plug that in and solve for P.
Thus, the perimeter of the shape is 69.
