Question 1210140
<br>
The problem is presented very poorly; and the only possible interpretation based on the given information describes a pyramid that is not possible.<br>
The problem says that ABCDE is a right pyramid whose base is a rhombus with side length 5, and that EA = BA = 2.  That does not describe the pyramid uniquely.<br>
The standard interpretation is that ABCD is the base and E is the peak of the pyramid.  But in that case, AB is 5 so the given information that BA is 2 is a contradiction.<br>
Since the side lengths of the base are all 5 and EA = BA = 2, that means A must be the peak of the pyramid, with BCDE as the base.<br>
But if that is the case, then face ABE of the pyramid is a triangle with side lengths 2, 2, and 5, which of course is not possible.<br>
SUMMARY....<br>
There is no possible interpretation of the information as given that leads to a problem that can be solved.<br>
