Answer:

x = 7

Explanation:

→ Find perimeter of rectangle

x + x + 4 + x + x + 4 = 4x + 8

→ Find perimeter of triangle

2x - 3 + 3x - 4 + x + 1 = 6x -6

→ Equate 2 expressions together

4x + 8 = 6x - 6

→ Minus 8 from both sides

4x = 6x - 14

→ Minus 6x from both sides

-2x = -14

→ Divide both sides by 2

x = 7
