Shown in the figure are 5 squares formed with 60 matchsticks.
The length of 1 stick is 1 unit. As an example, let's calculate the number of square units for the area labelled C:
= Total Area C - Total Area D
= (3 X 3) - (2 X 2)
= 5 square units
The challenge is to remove ALL the sticks of ANY 2 squares so that 2 of the 3 remaining areas have the same number of square units.
