Question

pan made a scale drawing of a swimming pool. The diving board is 2 inches long in the drawing. The actual diving board is 18 feet long. What scale did Pam use for the drawing?

Answer 1

Divide the length of the object on the drawing by its actual size to find the scale:

`\frac{2\text{ inches}}{18\text{ feet}}`

Since each feet has 12 inches:

`\frac{2\text{ inches}}{18\text{ feet}}=\frac{2\text{ inches}}{18\cdot12\text{ inches}}=(2)/(216)=(1)/(108)`

Therefore, the scale used in the drawing is 1:108 (one inch in the paper equals 108 inches in real life).
