Answer 1

If 2d is the length of a diagonal of a square and a is the length of its side, then
\[ d^2 + d^2 = a^2
\]
You have d, compute a then the area.

Answer 2

That is the side.

Answer 3

The area of a square can be found by taking one-half the product of its diagonals. Because the diagonals bisect each other, the segment shown in the diagram with length 12 is half a diagonal of 24. The diagonals of a square are congruent.

A = 1/2 (24*24)
A = 288 square units
