Weekly Problem 21 - 2006

Stage: 3 Challenge Level: Challenge Level:2 Challenge Level:2

84cm represents:
the height of the table minus the long side of a block plus the short side of a block.
96cm represents:
the height of the table plus the longside of a block minus the short side of a block.

So 84cm + 96cm represents two heights of the table.
The height of the table is therefore 90cm.

This problem is taken from the UKMT Mathematical Challenges.
