area of the triangle:
b*h/2
area of your triangle:
14*s/2 = ? what is the "shaded area"? Is it the area of the triangle or something else?
IF 84 is the area of the triangle:
14*s/2 = 84
14*s = 168
s = 14
Now, you say that the side of the triangle is 1/2s, so if that's the case the side of the triangle would be 1/2s = 14/2 = 7
