Here;
The porch extend in front of the house from diagram = \(19\frac{1}{2} - 18\) = \(1\frac{1}{2}\)

The porch extend by the side of the house from diagram = \(19\frac{1}{2}\) \(-(4 + 14\frac{1}{2})\) = \(19\frac{1}{2}\) \(- 18\frac{1}{2}\) = 1

Therefore the porch extend in front of the house than it does beyond the side of the house = \(1\frac{1}{2} - 1\)= \(\frac{1}{2}\)
