The formula for area of triangle, given two lengths and the included angle of the two lengths, is
1/2 x length 1 x length 2 x sin angle.
In this case DE and FE are the lengths and DEF is the included angle.
So in this case it’s 1/2 x 7 x 9 x sin 111 where the angle is measured in degrees, put in calculator and you will get the value for this area.
1/2 x length 1 x length 2 x sin angle.
