To find out how much longer the length of the room is compared to the width, you can subtract the width from the length:
Length = 18.586 feet
Width = 14.261 feet
Difference = Length - Width
Difference = 18.586 - 14.261
Difference = 4.325 feet
So, the length of the room is 4.325 feet longer than the width of the room. The correct answer is:
B. 4.325 feet
