Need to find:
- Perimeter of new square formed?

Solution:
- Side of smaller square = 3cm.
- Side of Bigger square = 9cm

Using formula:
- Perimeter of square = 4 × side

<u>Perimeter of smaller </u><u>square:</u>
⟹ 4 × 3
⟹ 12 cm

<u>Perimeter of Bigger square:</u>
⟹ 4 × 9
⟹ 36cm

Perimeter of new square = Perimeter of Bigger square - Perimeter of smaller square
⟹ 36 - 12
⟹ 24 cm

∴ Perimeter of new square formed is 24 cm.
