    area of a square = S^2

    S^2 = 123

    S = sqrt (123)

    S = 11.0905

    rounded to nearest tenth = 11.1 feet

    Area=side^2

    123ft²=side^2

    square root both sides

    estimate

    hmm

    12²=144

    11²=121

    so somewhere above 11 but below 12

    so like 11.1 (it's 11.09 so rounded it is 11.1)

    11.1ft
