Answer 1

28 units

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
