For a big dinner, Savannah needs to attach an extra piece to her dining room table. Without the extra piece, the table is 6 feet long and 3 feet wide. Attaching the extra piece to the table adds x feet to its length.
Pick all the expressions that represent the area of the table with the extra piece.
The area of a rectangle is given by the formula length times width. In this case, the length of the table with the extra piece is (6 + x) feet and the width remains the same at 3 feet. Therefore, the expression that represents the area of the table with the extra piece is:
(6 + x) * 3.
So the expression that represents the area of the table with the extra piece is:
1. (6 + x) * 3.
