@jiteshmeghwal9 pls help again :)) sorry to disturb you
OpenStudy (anonymous):
Diagonal of the square = Side x sqrt(2)
Area of the square = (side)^2
These are the basic theorems we should use.
Associating are of the square in terms of it's side, which is associated to the diagonal.
OpenStudy (anonymous):
D = 50 - 12sqrt(2)
D = (s)sqrt(2)
A = s^2
A = (50-12sqrt(2))^2/2
OpenStudy (anonymous):
\[A = {({50-12\sqrt{2})}^2}/2\]
OpenStudy (anonymous):
that cant be true if the side is\[50-12\sqrt{2}\]

I mean diagonal
is the diagonal \[5-12\sqrt{2}\]
or
\[(5-12)\sqrt{2}\]
OpenStudy (anonymous):
A = 545.47 cm^2
OpenStudy (anonymous):
If we consider \[50 - 12\sqrt{2}\] as the diagonal
OpenStudy (anonymous):
if it is\[50-12\sqrt{2}=(\frac{50}{\sqrt{2}}-12)\sqrt{2}\]
side\[50/\sqrt{2}-12\]
\[A=(\frac{ 50}{\sqrt{2}}-12)^2\]

Still the same answer
