qaws [65]

Answer:

28 units

Step-by-step explanation:

Since, given triangles have same perimeters.

\therefore \: 5x + 5x + 3x + 2 = 6x + 3 + 2x + 1 + 4x \\  \\ 13x + 2 = 12x + 4 \\  \\ 13x - 12x = 4 - 2 \\  \\ x =  2 \\  \\ \implies 12x + 2 = 12( 2) + 4 = 24 + 4 = 28 \: units \\  \\ \&\: 13x + 2 =13(2) + 2 = 26 + 2 = 28  \: units\\  \\

So perimeter of each triangle is 28 units
