    We have been given that Maria put trim around a banner that is the shape of a triangle. Each side is 21 inches long.

    The amount of trim will be equal to perimeter of triangle. The perimeter of given triangle will be 3 times each side length that is 3\times 21=63 inches.

    Now we need to convert 63 inches into feet.  

    12 inches = 1 feet

    63 inches = \frac{63}{12}  feet = 5.25 feet.

    We are also told that Maria has \frac{3}{4} foot of trim left, so total length of trim would be trim used plus trim left that is 5.25+\frac{3}{4}=5.25+0.75=6 feet.

    Since we need to find length of trim in yards, so we will convert 6 feet into yards.

    3 feet = 1 yard

    6 feet = \frac{6}{3} yards = 2 yards

    Therefore, the length of the trim was 2 yards.
