Largest possible area of the right #Delta ABC = color(green)(~~ 13.8564)# sq units

Three angles are #A = pi/2, B = pi/6, C = pi/3#

It is a right triangle with angles 30, 60, 90 and the sides will be in

the ratio of 1 : #sqrt3 # : 2

To get the largest are, side 4 should correspond to the least angle #pi/6#

Three sides will be #4, 4sqrt3, 8#

Largest possible area of the right #Delta ABC = (1/2) * 4 * 4sqrt3 color(green)(~~ 13.8564)# sq units
