Answer:
   x = 12 
   perimeter = 124
Step-by-step explanation:
The midline RS is half the length of MN, so we have ...
   2×RS = MN
   2(x +3) = 5x -30
   2x +6 = 5x -30
   36 = 3x . . . . . . . . . add 30-2x
   12 = x . . . . . . . . . . divide by 3
__
The length RS is then ...
   RS = x +3 = 15
and the perimeter of QRS is ...
   P(QRS) = QR +RS +SQ = 25 +15 +22 = 62
The perimeter of QRS is half the perimeter of MNP, so ...
   P(MNP) = 2×P(QRS) = 2×62 = 124
The perimeter of ΔMNP = 124.
 
        
             
        
        
        
Area of a circle = (3.14) * r^2
d = 7
r = 3.5
a = (3.14) * 3.5^2
a = (3.14) * 12.25
a = 38.47
