(a)
well in the 1st triangle you will have (blue)
P = 4x + 2 + 7x + 7 + 5x - 4
you need to collect like terms 
P = 16x + 5
Repeat the step for the red triangle 
(b) is simply the subtraction of the perimeters 
      P(blue) - P(red) = 16x + 5 - .........
(c) substitute x = 3
 P(blue) = 16(3) + 5
            = 53
hope this helps
