1:2:sqrt(3) is the ratio for the sides opposite 30:90:60 degree angles.
The hypotenuse is 2*14=28 cm. Therefore the length of every side from the standard ratio 1:2:sqrt(3) is multiplied by 14. Thus the sides are:
1*14=14, 28, 14*sqrt(3).
The perimeter is the sum of the sides' lengths which is:
14+28+14*sqrt(3) = approximately 66.25 cm.
