Question
Find the scale.
Actual size $12\ m$.
Drawing size $3\ cm$.
Actual size $12\ m$.
Drawing size $3\ cm$.
✓
Answer
By using,
$\text{Scale}=\frac{\text{Size drawn}}{\text{Actual size}}$
$=\frac{3\text{cm}}{12\text{cm}}$
$=\frac{1\text{cm}}{4\text{m}}=1\text{cm}:4\text{m}$
Hence, scale $= 1\ cm : 4\ cm$
$\text{Scale}=\frac{\text{Size drawn}}{\text{Actual size}}$
$=\frac{3\text{cm}}{12\text{cm}}$
$=\frac{1\text{cm}}{4\text{m}}=1\text{cm}:4\text{m}$
Hence, scale $= 1\ cm : 4\ cm$
