Randall is making a tablecloth for his dining room table. The table is 6 feet long and 3.5 feet wide. He also wants the tablecloth to have two triangular sections that fall off the edge of the table. The triangles need to be 3.5 feet wide and 1 foot tall.

What is the area of the completed tablecloth in square feet?

PLEASE HELP, PLEASE :)
