解法一：
public class Solution {
public int[] constructRectangle(int area) {
int length = (int) Math.ceil(Math.sqrt(area));//从平方根开始分界，求出长度的最大可能值
boolean isFind = true;
int[] res = new int[2];
while(isFind){
if(area % length == 0){
res[0] = length;
res[1] = area / length;
return res;
}
else{
length++;
}
}
return res;
}
}
