Answer:
Step-by-step explanation:
We have been given that the Rumpart family is building a new room onto their house. The width of the new room will be 16 feet.
The length of the room will be 4% greater than the width. This means that length of new room will be 16 feet plus 4% of 16.
Therefore, the expression represents the length of new room and the length of new room is 16.64 feet.
Since we know that area of a rectangular shape is width times length.
Therefore, the area of the new room will be 266.24 square feet.
