विकल्प

• 35 cm²

• 625 cm²

• 1225 cm²

• 2025 cm²

Answer 1

Perimeter of a square is 140 cm. ∴ Its area is 1225 cm².

Explanation:

The perimeter of a square is given by \(4 \times \text{side}\).

Given perimeter = 140 cm,

So, 4 × side = 140

⇒ Side = `140/4` = 35 cm

The area of a square is given by side².

So, area = 35 × 35 = 1225 cm².
