Question

Периметр параллелограмма равен 36 см. Найдите площадь параллелограмма, если его высота равна 4 см, а один из углов на 60 градусов меньше прямого.Помогите плиз

Answer 1

Угол = 90 - 60 = 30 град 
Одна из сторон параллелограмма = 
= высота / синус 30 = 4 / 1/2 = 8 см 
Вторая сторона = Р/2 - 8 = 36/2 = 10 см 
Площадь = 10 * 4 = 40 кв. см

Answer 2

Perimeter of the Parallelogram

The perimeter of a parallelogram is the sum of all its sides. To find the perimeter, we need to know the lengths of the sides of the parallelogram. However, the given information only includes the perimeter and the height of the parallelogram, as well as the measure of one of its angles. Without additional information, we cannot determine the lengths of the sides of the parallelogram. Therefore, we cannot calculate the perimeter of the parallelogram based on the given information.

Area of the Parallelogram

To find the area of a parallelogram, we can use the formula: Area = base × height, where the base is one of the sides of the parallelogram and the height is the perpendicular distance between the base and the opposite side.

In this case, the height of the parallelogram is given as 4 cm. However, we still need to determine the length of the base. The given information does not provide the length of the base or any other side of the parallelogram. Without this information, we cannot calculate the area of the parallelogram.

Therefore, based on the given information, we cannot determine the area of the parallelogram.
