Answer:
The answer to your question is: width = 3 meters
Step-by-step explanation:
Data
Perimeter = 16 meters
The room is 2 meters longer than its width, then length = width + 2
Perimeter = 2 length + 2 width
16 = 2(width + 2) + 2 width
16 = 2 width + 4 + 2 width
16 = 4 width +4
16 - 4 = 4 width
12 = 4 width
12/4 = width
3 = width
length = 3 + 2 = 5 meters
