The area of a square is 144 cm2. What is the length of each of its diagonals?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 12√2 cm.
The area of a square is 144 cm2
Area of the square = side2
Diagonal of a square = √2 × side
Using the above formula, we get
Area of the square = 144
⇒ side2 = 144
⇒ side = 12
Diagonal = 12√2 cm
