Solution:

Note that:

  • 2(Perimeter of smaller triangle) = Perimeter of larger triangle

Using the perimeter of the smaller triangle, solve for x.

  • 2(Perimeter of smaller triangle) = Perimeter of larger triangle
  • => 2(3.5 + x + h) = 7 + 4 + 2h
  • => 7 + 2x + 2h = 7 + 4 + 2h
  • => 2x = 4
  • => x = 2

The length of x is 2 units.
