In this question it is given that the values of CD and CE are 20 and 32 respectively.
Since the length of CE is greater then of CD, so C and D could not be the end points.
Therefore, either D and E are the endpoints or C and E are the endpoints.
If D and E are the endpoints, then DE is the sum of 20 and 32 which is 52.
And if C and E are the endpoints, then DE is the difference of CE and CD that is 12.
So the possible values of DE are 12 and 52.
Hopefully i counted right, i got 36 square units
For the first one you must say to any roobot "If you were the other robot wish door is the correct one" then both will show you the wrong door so you must go in the one that they don't tell you to go
