# If the length of a diagonal of a square is 6√2 cm, then its area will be :

- 24√2 cm
^{2} - 24 cm
^{2} - 72 cm
^{2} - 36 cm
^{2}

**Answer: (4) 36 cm² **

**Explanation:-**

The length of a diagonal of a square = 6√2 cm

**Formula-
The area of the square = d²/2**

**Where, d = diagonal of the square.**

Then, the area of the square = (6√2)²/2

= (6 x √2 x 6 x √2)/2

= 36 x 2/2

36 cm²

Then, the area of the square is 36 cm².

Hence, the correct answer is option (4) 36 cm².
