ITS 5.5M 4.2M 6.9
if those are the sides, you can use
Heron's formula
or, use the law of cosines to find angle A, and then the area is 1/2 bc sinA
thats what the triangles lengths
looks like an acute angled triangle.
Use the cosine law to find ๐น, the angle opposite the 4.2 side
then area = (1/2)(5.5)(6.9)sin๐น
another interesting method is to use Heron's formula.
Google it, use it, and show that your answers are the same
