To find : -

• Perimeter of square frame = ?

Solution : -

As we know that

• ★ Area of square = side × side

• → 1521 = (side)²

• → side = √1521

• → side = 39 cm

Now, perimeter of square.

• → 4 × side

• → 4 × 39

• → 156cm

Hence,

• Perimeter of square = 156cm

Extra Information : -

• Area of rectangle = length × breadth
• Perimeter of square = 2(length + breadth)
