    Answer:56 pack

    Step-by-step explanation:

    Length of backyard (L) = 32feet

    Width of backyard (W) = 21feet

    Area of backyard (A) = ?

    A=32x21

    A=672 square feet

    Each pack of seed cover 12 square feet

    Therefore 672/12pack will be needed to cover the whole area of the backyard

    672/12=56 pack will be needed
