Answer:
42
Step-by-step explanation:
Opposite sides of a parallelogram are congruent
You need to find the distance between Q(6, 6) and R(1, -6) using the distance formula.
PS = QR = [tex]\sqrt{(6 - 1)^{2} + (6 + 6)^{2} }[/tex]
= [tex]\sqrt{5^{2} + 12^{2} } = \sqrt{25 + 144} = \sqrt{169} = 13[/tex]
PQ = SR = 8
Perimeter = 13 + 13 + 8 + 8 = 42
