    We will use the formula:

    Area = 1/2*a*c*sinB

    where a and c are the length of the sides and B is the angle between those 2 sides

    Area = 1/2*5*8*sin42

    Area = 20*sin42

    sin 42 = 0.669130606359

    Area = 13.38261212718

    Rounded to the nearest tenth Area is equal to 13.4
