1.	If area of a square is 484 cm2. How long Its diagonal is:1. 44 cm2. 22√5 cm3. 22 cm4. 22√2 cm
Answer» Correct Answer - Option 4 : 22√2 cm Given: Area of square = 484 cm2 Formula Used: Area of square = side × side Diagonal = √2 × side Calculation Area of square = side × side ⇒ √484 = side ⇒ 22 cm = side Diagonal = √2 × side ⇒ Diagonal = √2 × 22 ⇒ Diagonal = 22√2 cm ∴ The length of the diagonal is 22√2 cm. The correct option is 4 i.e.22√2 cm.

Answer» Correct Answer - Option 4 : 22√2 cm

Given:

Area of square = 484 cm2

Formula Used:

Area of square = side × side

Diagonal = √2 × side

Calculation

Area of square = side × side

⇒ √484 = side

⇒ 22 cm = side

Diagonal = √2 × side

⇒ Diagonal = √2 × 22

⇒ Diagonal = 22√2 cm

∴ The length of the diagonal is 22√2 cm.

The correct option is 4 i.e.22√2 cm.
