mark me as brainlist. Thia answer is correct as i dont know the formulae for diagonal but .... i have done this by alternative method

Answer 2

side of the square a=10cm

diagonal of the square using Pythagoras theorem

d²=a²+a²

=2a²

d =√(2a²)

d= √(2)a

d= √(2)10

so by simplifying we get

so d=5√(2)

thats the final answer.
