To attach an extra piece to her dining room table, Savannah needs to add an extra x feet to its length.

Without the extra piece, the table is 6 ft long and 3 ft wide. Therefore, the original dimensions of the table are 6 ft (length) and 3 ft (width).

To attach the extra piece, Savannah will add x feet to the length. So, the new length of the table will be 6 ft + x ft.

Therefore, the dimensions of the extended table will be:
Length: 6 ft + x ft
Width: 3 ft
