Question

The blueprint (a scale drawing used by architects and others) for Zahra’s new office measures `4` cm long and `2` cm wide. The scale for the blueprint is `6` cm to `15` ft. What is the length and width of her actual office?

Answer 1

Using scale concepts, it is found that the length of her office is of 10 ft, while the width is of 5 ft.

------------------------

• The scale of 6 cm to 15 ft means that each 6 cm in the drawing represent 15 ft in actual dimensions.
• From this, a rule of three is applied to find the dimensions.

First, we find the actual length:

6 cm - 15 ft

4 cm - x ft

$6x = 60$

$x = \frac{60}{6}$

$x = 10$

The actual length is of 10 ft.

Then, we find the actual width:

6 cm - 15 ft

2 cm - x ft

$6x = 30$

$x = \frac{30}{6}$

$x = 5$

The actual width is of 5 ft.
