Question

Высота комнаты - 2 м, длина комнаты в 5 раз больше высоты,а ширина на 4 см меньше. определи периметр и площадь этого листа. помогите пожалуйста

Answer 1

длина = 2*5=10м
ширина = 1,96м
Периметр = (10+1,96)*2=23,92 м
S = 10*1.96=19.6 кв.м

Answer 2

Task: Calculating the Perimeter and Area of a Room

To calculate the perimeter and area of a room, we need to know the height, length, and width of the room. Let's break down the given information:

- Height of the room: 2 meters - Length of the room: 5 times the height (10 meters) - Width of the room: 4 centimeters less than the height

Calculating the Perimeter

The perimeter of a rectangle is the sum of all its sides. In this case, the room is a rectangular shape, so we can calculate the perimeter using the formula:

Perimeter = 2 * (Length + Width)

Let's substitute the values we have:

- Length = 10 meters - Width = Height - 4 centimeters

To calculate the width in meters, we need to convert the width from centimeters to meters. Since 1 meter is equal to 100 centimeters, the width in meters would be:

Width = (Height - 4) / 100 meters

Now we can calculate the perimeter:

Perimeter = 2 * (Length + Width)

Perimeter = 2 * (10 + (Height - 4) / 100)

Calculating the Area

The area of a rectangle is calculated by multiplying its length and width. In this case, the formula for the area is:

Area = Length * Width

Let's substitute the values we have:

- Length = 10 meters - Width = Height - 4 centimeters

Again, we need to convert the width from centimeters to meters:

Width = (Height - 4) / 100 meters

Now we can calculate the area:

Area = Length * Width

Area = 10 * (Height - 4) / 100

Calculation Results

To summarize, the formulas for calculating the perimeter and area of the room are:

Perimeter = 2 * (10 + (Height - 4) / 100) meters

Area = 10 * (Height - 4) / 100 square meters

Please provide the height of the room in meters, and I will calculate the perimeter and area for you.
