# Three squares are attached to each other as shown in Fig. 9.37. Each square is attached at the midpoint of the side of the square to its right. Find the perimeter of the complete figure.

**Solution:**

Given, three __squares__ are attached to each other

Each square is attached at the midpoint of the side of the square to its right.

We have to find the perimeter of the complete figure.

Considering Square 1,

The side of square 1 is 6 m.

Considering square 2,

Given, square 2 is attached at the midpoint square 1.

Midpoint of square 1 = 6/2 = 3 cm

The side of square 2 is 3 cm

Considering square 3,

Given, square 3 is attached at the midpoint of square 2.

Midpoint of square 2 = 3/2 = 1.5 cm

The side of square 3 is 1.5 cm

__Perimeter__ = sum of all sides

So, perimeter of the given figure = 6 + 3 + 3 + 1.5 + 1.5 + 1.5 + 1.5 + 3 + 6 + 6

= 18 + 9 + 6

= 33 cm

Therefore, the perimeter of the complete figure is 33 cm.
