    1. A = 100Ft^2.
    L = sqrt(100)= 10Ft. = Length of each side.
    10Ft/side * 4sides = 40 Ft.


    3. A perfect square is a number whose square root is a whole number:
    9, 25, 144 and 36 are perfect squares, because their square root is a whole number.

    4. sqrt(625) = 25 Ft./side.

    5. Correct.
