Answer 2

Answer:    Total measure of all exterior angles = 360°  

  x + 90° + 50° + 110° = 360°        

              x + 250° = 360°  

                     x = 110°

Step-by-step explanation:

In a parallelogram, the opposite sides have same length.  

 Therefore, PQ = SR = 12 cm and QR = PS = 7 cm

 So, Perimeter = PQ + QR + RS + SP

 = 12 cm + 7 cm + 12 cm + 7 cm  

 = 38 cm
