Answer 2

Answer:

this (^) sign between bracket means square

area of square is d^/2

Step-by-step explanation:

let the side of square be x

so according to Pythagoras theorem,

x^+x^=d^

2x^=d^

root both side,we get

√2x=d

so,x=d/√2

so, side of square is d/√2.

now,

area of square=x^

=(d/√2)^

=d^/2.

now please tell me how to put square on any no..
