A point in a square is connected to the midpoints of its sides, dividing the square into four regions. The areas of three of the regions are labelled. Find the area of the fourth region.
The area of the fourth region is 32.
Maybe your teacher wants you to answer 40 but it would not be right.
This set of areas is impossible. So there is no answer.
If one area is 12 or less than 12, all the other areas MUST be more than 12.
