Question

If a square sheet has perimeter of 120 cm , then what is its
anea ? З​

Answer 1

Answer:

• Area of a square sheet is 900 cm².

Step-by-step explanation:

Given that:

• A square sheet has perimeter of 120 cm.

To Find:

• Area of a square sheet.

Formula used:

• Perimeter of a square = 4 × (side)
• Area of a square = (side × side)

Finding the side of a square sheet:

⟶ 120 cm = 4 × (side)

⟶ side = (120 cm)/4

⟶ side = 30 cm

Finding the area of a square sheet:

⟶ Area of a square = (30 cm × 30 cm)

⟶ Area of a square = 900 cm²

Answer 2

Given

• Perimeter of a square sheet = 120 cm

To find

• Area of the square sheet

Solution

• Perimeter of square = 4 × side
• 120 = 4 × side
• side = 120/4
• side = 30

Hence, the side of square is 30 cm

• Area of square = side × side
• Area = 30 × 30
• Area = 900

Hence, the area of square/square sheet is 900 cm²
