Question

Ширина комнаты прямоугольной формы 7мм, это в 2 раза меньше ее длины. Найдите площадь комнаты

Answer 1

1) 7мм × 2 = 14мм ( длина комнаты.)
2) Формула площади прямоугольника: а × b
    a = 7мм
    b = 14мм
    а × b = 7мм × 14 мм = 98мм² ( площадь комнаты.)
Ответ: площадь комнаты равен 98мм².

Answer 2

1)7*2=14длина
2)14*7=98м²

Answer 3

Calculating the Area of a Rectangular Room

To find the area of a rectangular room, we can use the formula: Area = Length x Width. Given that the width of the room is 7m and it is 2 times smaller than its length, we can calculate the area using the provided information.

Calculation

The length of the room can be calculated as follows: - Let's assume the length of the room is L meters. - According to the given information, the width is 7m and it is 2 times smaller than the length. This can be represented as: Width = 7m and Length = 2 * Width.

Using this information, we can calculate the length of the room.

Solution

The length of the room can be calculated as: - Length = 2 * Width - Length = 2 * 7m - Length = 14m

Now that we have the length and width of the room, we can calculate the area using the formula: - Area = Length x Width - Area = 14m x 7m - Area = 98 square meters

So, the area of the rectangular room is 98 square meters.
