Answer:

  • x = 2 feet

Step-by-step explanation:

We know that the perimeter is the sum of side lengths.

  • P = a + b + c

Substitute the values and solve for x:

  • x + 2x - 2 + 3x + 1.5 = 11.5
  • 6x - 0.5 = 11.5
  • 6x = 12
  • x = 12/6
  • x = 2

Answer:

[tex]perimeter = h + l + b \\ = x + 2x - 2 + 3x + 1.5 = 11.5 \\ x \: terms \: togather \\ x + 2x + 3 x- 2 + 1.5 = 11.5 \\ 6x - .5 = 11.5 \\ 6x = 11.5 + .5 \\ 6x = 12 \\ x = \frac{12}{6} \\ x = 2 \\ thank \: you[/tex]
