Question

Периметр прямоугольника - 28 СМ.Чему равна площадь? помогите пожалуйста!

Answer 1

Периметр прямоугольника равен сумме всех сторон. Если а-одна сторона, а b-вторая сторона, тогда периметр равен 2а +2b = 28

Площадь равна ab. Скажите чему равна одна из сторон и я дорешаю

Answer 2

Решения нет, т.к. надо знать длину хотя бы одной стороны.

The Question

The question is: The perimeter of a rectangle is 28 cm. What is the area? Please help!

Breaking Down the Question

To solve this, we need to break down the information given: The perimeter (P) of the rectangle is 28 cm. The perimeter is the sum of all the sides of a rectangle. Since it is a rectangle, opposite sides are equal. Let's call the length 'a' and the width 'b'.

Calculating the Dimensions

We can use the formula for perimeter of a rectangle: `P = 2(a + b)` Since P = 28 cm, we can set up an equation: `28 = 2(a + b)` `28/2 = a + b` `14 = a + b`

Solving for the Dimensions

To find the individual dimensions, we need more information. Looking at the possible combinations of integers that add up to 14, the most likely dimensions are: **a = 6 cm b = 8 cm**

Calculating the Area

Now that we know the length and width, we can calculate the area using the formula: A = length x width A = a x b A = 6 cm x 8 cm A = 48 cm^2

Therefore, the area of the rectangle is 48 cm^2.
