Answer
$\frac{1}{2}$ acre
Work Step by Step
Let us consider that a homeowner has a lot that measures 1$\frac{1}{2}$ acres, of that area $\frac{1}{2}$ acres is wooded , $\frac{1}{6}$ acres is covered by house , $\frac{1}{3}$ acres is covered by driveway
Area covered by lawn = 1$\frac{1}{2}$ -$\frac{1}{2}$ -$\frac{1}{6}$ - $\frac{1}{3}$
=$\frac{3}{2}$ -$\frac{1}{2}$ -$\frac{1}{6}$ - $\frac{1}{3}$
= $\frac{2}{2}\times$ $\frac{3}{3}$ -$\frac{1}{6}$ - $\frac{1}{3}\times$ $\frac{2}{2}$
=$\frac{6}{6}$ -$\frac{1}{6}$ -$\frac{2}{6}$
=$\frac{3}{6}$
=$\frac{1}{2}$ acre
