Answer

$93.6$ square centimeters.

Work Step by Step

If we know two sides of the triangle and their enclosed angle, we multiply half the product of the sides by the sine of their enclosed angle, to obtain the area of the triangle. Hence here the area: $0.5\cdot44.4\cdot22.2\cdot\sin(21.8)\approx93.6$ square centimeters.
