The following three subjects are mistake problems actually set to the junior high school entrance examination.
This a problem setting-mistake is not discovered recently.
It carries as a monumental mistake here.
On the problem on which two roads intersect rectangular land,
if at least one side is parallel to the neighborhood, an answer canbe found.
When two roads are not parallel to the rectangular neighborhood.
We can not solve that problem.
Area changes with angles of an intersection of two roads.
Be careful.
