Answer:
A
Step-by-step explanation:
To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.
3 (length of the window) X 2 = 6
10 (perimete) - 6 = 4
4 / 2 = 2m
