Question

Прямоугольник АВСД имеет длину 5 см а ширину 3 см.Вычислите его периметр. Мне эту задачу надо решить тремя способами плииз срочно надо заранее спасибо.

Answer 1

(5+5)+(3+3)=16
5×2+3×2=16
5+5=10 3+3=6 10+6=16

Answer 2

5+5+3+3=16см 5*2+3*2=16см (5+3)*2=16см

Answer 3

Calculation of Perimeter of Rectangle ABCD

To calculate the perimeter of a rectangle, we need to add up the lengths of all four sides. In this case, the rectangle ABCD has a length of 5 cm and a width of 3 cm.

Method 1: Using the Formula

The formula to calculate the perimeter of a rectangle is:

Perimeter = 2 * (Length + Width)

Substituting the given values, we get:

Perimeter = 2 * (5 cm + 3 cm) = 2 * 8 cm = 16 cm

Therefore, the perimeter of rectangle ABCD is 16 cm.

Method 2: Adding All Sides

Another way to calculate the perimeter is by adding the lengths of all four sides. In this case, we have two sides with a length of 5 cm and two sides with a length of 3 cm.

Adding all the sides, we get:

Perimeter = 5 cm + 5 cm + 3 cm + 3 cm = 16 cm

Again, we find that the perimeter of rectangle ABCD is 16 cm.

Method 3: Using the Given Snippet

Based on the search snippet provided, it seems that the snippet does not contain the specific information needed to calculate the perimeter of the rectangle. Therefore, we cannot use this snippet to solve the problem.

In conclusion, the perimeter of rectangle ABCD is 16 cm, which can be calculated using either the formula or by adding all four sides.
