Guessing an acute angle, taking the longer side as the base, the shorter side multiplied by sine of the angle is the height. Area is (1/2)(b)*h, or how I just described, Area = , assuming name of the angle is x.

From obtain
sin(x)=0.73745, degrees.

In this picture below, the two sides of the triangle are shown, and the height is shown; but the third triangle side is not shown.
