The blueprint 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 actual area of her office?

Answer:

60 square feet

Explanation:

In the blue print, 6 cm represents 15 ft

So 1 cm represents 15/6 feet = 5/2 feet

4 cm long represents 4 x 5/2 = 10'

2 cm wide represents 2 x 5/2 = 5'

Area = 10' x 5' = 60 square feet
