  • P = 70cm

[tex]\large\rm{SOLUTION:}[/tex]

Looking at the image above,

the measures of the sides of triangle would be

  • a = 8 + 15 = 23cm
  • b = 8 + 12 = 20cm
  • c = 12 + 15 = 27cm

[tex]{}[/tex]

The perimeter of triangle is

  • P = a + b + c
  • P = 23 + 20 + 27
  • [tex]\boxed{ \mathsf{P\:=\:70cm}}[/tex]
