Given two sides and the angle between them, you can use the formula:
Area = 1/2*a*b*sinѲ
Where a and b are the sides, and Ѳ the angle between them.

Using the cosine and sine rules the area of the triangle works out as 457 square cm rounded.
If you know the lengths of two sides, a and b, and the included angle, C, then area = 0.5*a*b*sin(C)
The answer depends on what other information you have about the triangle.
Using the cosine rule angles of the triangle are: 119.10 degrees, 31.99 degrees and 28.91 degrees all rounded to two decimal places. Using sine area formula its area is: 3.24 square cm rounded to two decimal places.
Using the cosine and sine rules in trigonometry the angles are 51.05 degrees, 85.11 degrees and 43.84 degrees with an area of 18.17 square cm.
