Question

Как найти площадь:квадрата, прямоугольника , треугольника и периметр . Заранее БОЛЬШОЕ СПАСИБО, ЛЮБИМЫЕ !

Answer 1

(Формулы)
Квадрат - P= 4*а
Прямоугольника - P= 2*(а+в)
Треугольника - P= а+в+с

Квадрат - S=а2=2см2=2*2=4
Прямоугольник - S= а*в
Треугольник - S=1
                            -- bh
                            2

Answer 2

Площадь квадрата-a*a(т.е.одну сторону уножить на другую)
Площадь прямокгольника-a*b(т.е. одну сторону умножить на другую)
Площадь треугольника равна половине произведения длины стороны треугольника на длину проведенной к этой стороне высоты
S = 1a · h.
Там очень сложно.

Answer 3

Finding the Area of a Square

To find the area of a square, you need to know the length of one side. The formula for finding the area of a square is:

Area of a square = side length * side length

For example, if the side length of a square is 5 units, the area would be:

Area = 5 * 5 = 25 square units

Finding the Area of a Rectangle

To find the area of a rectangle, you need to know the length and width of the rectangle. The formula for finding the area of a rectangle is:

Area of a rectangle = length * width

For example, if the length of a rectangle is 6 units and the width is 4 units, the area would be:

Area = 6 * 4 = 24 square units

Finding the Area of a Triangle

To find the area of a triangle, you need to know the base and height of the triangle. The formula for finding the area of a triangle is:

Area of a triangle = (base * height) / 2

For example, if the base of a triangle is 8 units and the height is 6 units, the area would be:

Area = (8 * 6) / 2 = 24 square units

Finding the Perimeter of a Shape

The perimeter of a shape is the total length of its boundary. The formulas for finding the perimeter of different shapes are as follows:

- For a square: Perimeter = 4 * side length - For a rectangle: Perimeter = 2 * (length + width) - For a triangle: Perimeter = side1 + side2 + side3

For example, if the side length of a square is 5 units, the perimeter would be:

Perimeter = 4 * 5 = 20 units

If the length of a rectangle is 6 units and the width is 4 units, the perimeter would be:

Perimeter = 2 * (6 + 4) = 20 units

If the lengths of the sides of a triangle are 3 units, 4 units, and 5 units, the perimeter would be:

Perimeter = 3 + 4 + 5 = 12 units
