There are various formulas for finding the area of a parallelogram:
S = a * ha.
a = 11 (by condition);
ha = 3 (the height of the parallelogram is the leg opposite an angle of 30 °, equal to half of the hypotenuse, in a right-angled triangle, where the hypotenuse is the second side of the parallelogram).
S = 11 * 3 = 33.
If the sinuses have already passed, then we use the following formula:
S = a * b * sinα = 11 * 6 * sin 30 ° = 11 * 6 * 1/2 = 33.
Answer: the area of the parallelogram is 33 square units.
