Answer:

  • 124 in

Step-by-step explanation:

Use ratios to find x and y, then find AB and GH, them sum up the lengths.

Find x:

  • 12/15 = x/10
  • x = 12*10/15
  • x = 8 in

Find y:

  • 12/15 = 16/y
  • y = 15*16/12
  • y = 20 in

Find AB:

  • y - 14 = 20 - 14 = 6 in

Find GH:

  • 5x - 3 = 5*8 - 3 = 37 in

Find the perimeter:

  • P = 6 + 15 + 20 + 10 + 37 + 8 + 16 + 12 = 124 in
