sq. root of (80/125)= sq. root of [(9)(2)(5)/(25)(5)]= (sq. root of 9)(sq. root of 2)/sq. root of 25= (3/5)sq. root of 2
sq. root of 75 = sq. root of (25 x 3) = (sq. root of 25)(sq. root of 3) = 5(sq. root of 3)
11.18033989 is the sq. root of 125.

9 sq ft = 1 sq yd so 80 sq ft = 80/9 = 8.88... sq yards.
sq root (112.7) = 10.6160256.... sq root (112.7) = 10.6160256....
80 yd2 is 66.9m2
Because: tan(60) = square root of 3
