Answer:
Step-by-step explanation:
A rectangular room must have a perimeter of 20 feet and an area of at least 20 square feet. Describe the possible widths of the room. Round your answers to the nearest tenth of a foot
------------
L + W = 10 --> W = 10 - L
---
L*W >= 20
----
Solve L*W = 20
L*(10 - L) = 20
-L^2 + 10L - 20 = 0
