网考网试题解析：
You need to know the product of A and B to solve this question. (1) alone is insufficient because it does not give the value for A, although you can infer from the Pythagorean theorem that B=3. (2) alone is insufficient because (A, B) could be (1, 6) or it could be (3, 4), there is no way to tell. If the statements are combined, you can take the value that B=3 and determine from the equation in statement (2) that A=4; therefore, the area of the rectangle is 12. document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
