Answer 1

Answer:

8.67 cm

Step-by-step explanation:

Perimeter of the triangle = 3 * side = 3 (2x + 3) = (6x + 9) cm

Perimeter of the figure = 4 * perimeter of the triangle = 4 (6x + 9)

= (24x + 36) cm

104 = 24x + 36

⇒ 24x = 104 - 36

⇒ 24x = 68

⇒ x = 68 ÷ 24

⇒ x = 2.83

2x + 3 = (2 * 2.83) + 3 = 5.67 + 3 = 8.67 cm

So, the length of the side of the triangle is 8.67 cm and the length of the side of the square is 8.67 cm.
