Question
Find the scale. Actual size $45$ feet. Drawing size $5$ inches.
✓
Answer
By using, $\text{Scale}=\frac{\text{size drawn}}{\text{Actual size}}=\frac{5\text{inches}}{45\text{feet}}$
$=\frac{1 \text{ inch}}{9\text{ feet}}=1\text{ inch}:9\text{ feet}$
Hence, scale = $1$ inch : $9$ feet
$=\frac{1 \text{ inch}}{9\text{ feet}}=1\text{ inch}:9\text{ feet}$
Hence, scale = $1$ inch : $9$ feet
