Q8:

A certain right triangle has sides of length x, y, and z, where x < y < z. If the area of this triangular region is 1, which of the following indicates all of the possible values of y ?
A. y > 根号2
B. 根号3/2< y <根号2
C. 根号2/3< y <根号3/2
D. 根号3/4< y <根号2/3
E. y < 根号3/4

怎么解？不好意思，根号符号表达不出来，用文字代替了。

xy=2, and y is smaller than x, so x<y<infinitude, when x=y,y is 2^1/2, so A is right.
