    The area of a rectangle is the product of its length and width:

    (7 yds) (3 yds) = 21 square yds.

    We must convert this to square feet. Note that 1 sq yd = 27 sq ft.

    Thus, (21 sq yd) times (27 sq ft / 1 sq yd) = 21 (27) sq ft. Finish this by multiplying 21 and 27 together. Be sure to include the units of measurement.

    21 square feet. Area equals width x lengths. 7*3=21
