Question

Методом подбора определи,какими могут быть длина и ширина прямоугольника,если его площадь равна 20кв.см. Построй треугольник с площадью 10кв.см. Если можно с рисунком за ранее спасибо!!!!!!!!!!!

Answer 1

Площадь прямоугольника:
S = а * в,

значит:

размеры прямоугольника:
длина а    ширина в:
   20               1,
   10               2,
     5               4,

Answer 2

Determining the Dimensions of a Rectangle with an Area of 20 sq. cm

To determine the possible dimensions of a rectangle with an area of 20 sq. cm, we can use the method of trial and error. The formula for the area of a rectangle is given by:

Area = Length × Width

Given that the area is 20 sq. cm, we can start by trying different combinations of length and width until we find the pair that satisfies the given area.

Let's start by trying some combinations:

1. Length = 1 cm, Width = 20 cm 2. Length = 2 cm, Width = 10 cm 3. Length = 4 cm, Width = 5 cm

By trying these combinations, we can determine the dimensions of the rectangle that satisfy the given area.

Triangle with an Area of 10 sq. cm

To construct a triangle with an area of 10 sq. cm, we can consider different types of triangles such as equilateral, isosceles, or scalene. The formula for the area of a triangle is given by:

Area = (Base × Height) / 2

We can use this formula to calculate the dimensions of the triangle with the given area.

If you have specific preferences for the type of triangle or any particular dimensions, please let me know so I can provide a more tailored example.

I hope this helps! If you have any further questions or need additional assistance, feel free to ask.
