Question

Помогите я не могу решить задачу с иксом объясните пожалуйста. Заранее спасибо! Начерти прямоугольник , периметр которого равен =200мм т.е-20см ,а длина одной стороны в 3 раза больше,чем длина другой стороны Спасибо! и можно быстрей

Answer 1

200 мм = 20 см
20 : 2 = 10 ( см ) сумма длины и ширины
10 : ( 3 + 1 ) = 10 : 4 = 2,5 ( см ) ширина
2,5 • 3 = 7,5 ( см ) длина
Ответ чертим прямоугольник с длиной 7,5 см и шириной 2,5 см

Answer 2

Drawing a Rectangle with a Perimeter of 200mm

To solve the problem, we need to draw a rectangle with a perimeter of 200mm (or 20cm) where one side is three times longer than the other side.

Let's assume the length of one side is x mm. According to the problem, the other side will be three times longer, so its length will be 3x mm.

The perimeter of a rectangle is calculated by adding the lengths of all four sides. In this case, we have two sides of length x mm and two sides of length 3x mm.

The equation for the perimeter of the rectangle can be written as:

2x + 2(3x) = 200

Simplifying the equation:

2x + 6x = 200

8x = 200

Now, we can solve for x:

x = 200 / 8

x = 25

So, one side of the rectangle is 25mm, and the other side is three times longer, which is 75mm.

To draw the rectangle, you can use a ruler or any other measuring tool. Start by drawing a line segment of 25mm, and then draw another line segment of 75mm perpendicular to the first line segment. Connect the endpoints of the line segments to form a rectangle.

I hope this explanation helps you solve the problem and draw the rectangle correctly. Let me know if you have any further questions!
