For this case we must solve the following equation:
We group the variable terms of the left side of the equation, the terms that are adding from one side pass to the other side subtracting and vice versa:
Thus, the value of the variable is 11.76

Answer:
The perimeter is
Step-by-step explanation:
we know that
A parallelogram is a quadrilateral where both pairs of opposite sides are parallel and equal
so
In this problem
PS=QR ----> equation A
SR=PQ ----> equation B
The perimeter of parallelogram PQRS is
P=PQ+QR+SR+PS ----> equation C
substitute equation A and equation B in equation C
we have
substitute in the formula of perimeter
