Answer:

Let us consider a square ABCD with diagonals intersecting at ‘O’.

OP is perpendicular to any of its sides such that

OP = 2√2 cm

Let the side of square be ‘L’

Then diagonal of square, BD = L√2

Also,

Diagonals of square bisect each other, therefore

OD=OB=BD/2

OD=L√2/2

Also, By symmetry

DP=CP=CD/2=L/2

Now, In ΔOPD, By Pythagoras theorem

Hypotenuse^2 = Perpendicular^2 + Base^2

⇒ OD^2 = OP^2 + DP^2

(L√2/2) ^2=(2√2) ^2+(l/2) ^2

L^2/4=8

⇒ L^2= 32

⇒ L^2= 4√2 cm

Step-by-step explanation:

I think this is the answer
