Question

Периметр прямоугольника 66 дм. Длина его одной стороны составляет 3\11 периметра. Найдите площадь прямоугольника

Answer 1

Находим длину одной стороны
3/11 на 66 дм равно 18 дм
тогда дина другой стороны 66 - 18х2 = 30 дм
30/2 = 15 дм
получается прямоугольник с длинами сторон 15 и 18 дм
площадь прямоугольника 15 х 18 = 270 кв. Дм

Answer 2

Calculation of the Rectangle's Perimeter

To find the area of a rectangle, we first need to calculate its perimeter. The problem states that the perimeter of the rectangle is 66 dm, and the length of one side is 3/11 of the perimeter.

Let's assume the length of the rectangle is 'a' and the width is 'b'. According to the problem, we have the following information:

Perimeter of the rectangle (P) = 66 dm Length of one side (a) = 3/11 * P

To find the perimeter, we can use the formula: P = 2(a + b)

Substituting the given values, we have: 66 = 2(3/11 * P + b)

Simplifying the equation, we get: 33 = 3/11 * P + b

Now, we need to find the value of 'b' in terms of 'P': b = 33 - 3/11 * P

Calculation of the Rectangle's Area

The area of a rectangle can be calculated using the formula: Area = length * width

Substituting the values we have: Area = (3/11 * P) * (33 - 3/11 * P)

Simplifying the equation, we get: Area = (3P/11) * (33 - 3P/11)

To find the exact value of the area, we need to know the value of 'P'. Unfortunately, the problem does not provide the exact value of 'P'. Therefore, we cannot calculate the exact area of the rectangle without this information.

If you have the exact value of 'P', please provide it, and I will be happy to help you calculate the area of the rectangle.
