    These were the answer choices you posted last week.

    1 foot
    2 feet
    3 feet
    4 feet

    Your problem has a major error in it.

    First this blanket would large enough to cover a large bedroom -- about 10 by 17 feet.

    Looking at your answer choices:
    2 feet squared = 4 square feet
    4 * 30 = 120 sq. ft.

    3 feet squared = 9 square feet
    9 * 30 = 270 square feet

    4 feet squared = 16 sq. ft.
    16 * 30 = 480 sq. ft.

    As you can see, none of the answers comes close.

    Please check with your teacher about this problem.

    6s x 5s = 170
    30s^2 = 170
    s^2 = 170/30
    s^2 = 5.67
    s = 2.38

    s = 2 ft
