    Answer:

    886.13sq. units

    Step-by-step explanation:

    If the figure is a triangle

    Area of the triangle =  1/2 ab sintheta

    Given

    a = 41 units

    b = 23 units

    theta = 70°

    Area of the triangle  = 1/2 * 41 * 23 sin 70

    Area of the triangle = 943 sin70

    Area of the triangle = 943(0.9397)

    Area of the triangle = 886.13

    Hence the area of the triangle is 886.13sq. units
