Triangle XYZ is an isosceles right triangle. If side XY is longer than side YZ, and the area of the triangle is 36, what is the measure of side XY?  Choose the correct choice from the following choices
A) 4	B) 4 √ 2	C) 12	D) 8 √ 2	E) can not be determined from the information provided

Rationale: "ans c . . 12 . . xy being larger means it is the hyp . . area = ( 1 / 2 ) * ( yz ) ^ 2 = 36 or yz = 3 * \ sqrt { 2 } . . therefore hyp = xy = 12"
Answer: C
