Question

Как найти площади всех фигур (трапеция, треугольник, параллелограмм, ромб)

Answer 1

Площадь треугольника : S=ab:2

Answer 2

Finding the Areas of Different Shapes

To find the areas of different shapes such as trapezoid, triangle, parallelogram, and rhombus, you can use specific formulas and methods for each shape.

Trapezoid: To find the area of a trapezoid, you can use the formula: \[ A = \frac{1}{2}h(b_1 + b_2) \] Where: - \( A \) = Area - \( h \) = Height of the trapezoid - \( b_1 \) and \( b_2 \) = Lengths of the parallel sides

Triangle: The area of a triangle can be calculated using the formula: \[ A = \frac{1}{2}bh \] Where: - \( A \) = Area - \( b \) = Length of the base - \( h \) = Height of the triangle

Parallelogram: The area of a parallelogram can be found using the formula: \[ A = bh \] Where: - \( A \) = Area - \( b \) = Length of the base - \( h \) = Height of the parallelogram

Rhombus: The area of a rhombus can be calculated using the formula: \[ A = \frac{1}{2}d_1d_2 \] Where: - \( A \) = Area - \( d_1 \) and \( d_2 \) = Lengths of the diagonals

These formulas can be used to find the areas of the respective shapes.
