Fiona purchased 400 m2 of plastic sheeting and needs to cut it into rectangles of area 500 cm2. This can be done with no waste. How many rectangles can fiona cut?

8000

Step-by-step explanation:

The number will be ...

(400 m^2) / (500 cm^2) = 0.8 (m/cm) ^2 = 0.8 ((100 cm) / (1 cm)) ^2

= 0.8·100^2 = 8000

Fiona can cut 8000 rectangles from the plastic sheeting she bought.
