Question

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 1

Answer: 20 ft^2

Step-by-step explanation:

15 ft:6 cm = x: 4*2 cm^2

15 ft:6 cm = x: 8 cm^2

15/6=x/8

15*8/6=x

x=120/6

x=20 ft^2
