Tip: Ignore the squares and consider the relationship between the rows of matches and columns of matches in a grid.
Tip: The number of matches needed to form a columns \(a\) units high will always be one greater than \(b\).
From this information, write an expression to represent the number of matches in columns.
Tip: Combine these two expressions to form an equation that equals the number of matches stated in the question: \(337\)
Tip: We cannot find the answer using the current form of the equation.
If you multiply the equation by \(2\) you can factorise the expression of the number matches.
