  1. No. the area of a square is s^2, where s is a side length
    s^2=121
    take the square root of each side
    s=11ft

  2. the side times the side = 121
    Something times itself is 121
    It is not 9 because 9*9 = 81
    It is not 10 because 10*10 = 100
    Is it 11?
    What is 11 times 11?
