Answer 2

Answer:

12√2 cm

Step-by-step explanation:

Information provided to us,

Side of square, s = 12 cm

We know that,

Diagonal of a square = √[2(side)² ]

Hence, we are provided the required information i.e. measurement of the side of the square.

Diagonal of the square, d = √[2 * 12²]

d = √[2 * 144]

d = 12√2 cm

Diagonal of the square = 12√2 cm

You may also proceed forward with calculation by substituting the value of √2 but the above answer is also accepted.
