Hi there
Given :
Area of the triangle = 12 sq cm.
The two sides of the triangle, AB = 8 cm and AC = 6 cm.
Let the <BAC = theta.
[AB*AC*sin BAC]/2 = 12, or
sin BAC = [2*12]/[8*6] = 0.5
Hence <BAC = 30 deg.
So we can have one triangle with AB = 8 cm, AC = 6 cm and <BAC = 30 deg, and its area will be 12 sq cm.
