Question

Деление суммы на число Реши задачу. Напиши ответ. Длина первого сада прямоугольной формы 80 м, а ширина в 4 раза меньше. Определи длину второго сада, если известно, что периметр его в 3 раза больше периметра первого сада и имеет ширину 60 м. Ответ: M​

Answer 1

Ответ:

240м

Пошаговое объяснение:

80:4=20м ширина 1 сада

P=2(a+b)

Р= 2(80+20)=200м периметр 1 сада

200×3=600м периметр 2 сада

600÷2-60=240м длина 2 сада

Answer 2

Problem Analysis

We are given the length of the first garden, which is rectangular and measures 80 meters. The width of the first garden is 4 times smaller than its length. We need to determine the length of the second garden, given that its perimeter is 3 times larger than the perimeter of the first garden and its width is 60 meters.

Solution

To solve this problem, we can use the formula for the perimeter of a rectangle, which is given by the equation:

Perimeter = 2 * (Length + Width)

Let's calculate the perimeter of the first garden using the given information:

Length of the first garden = 80 meters Width of the first garden = 4 times smaller than its length = 80 / 4 = 20 meters

Using the formula for the perimeter, we can calculate:

Perimeter of the first garden = 2 * (Length + Width) = 2 * (80 + 20) = 2 * 100 = 200 meters

Now, we are given that the perimeter of the second garden is 3 times larger than the perimeter of the first garden. Let's calculate the perimeter of the second garden:

Perimeter of the second garden = 3 * Perimeter of the first garden = 3 * 200 = 600 meters

We are also given that the width of the second garden is 60 meters. Using the formula for the perimeter, we can calculate the length of the second garden:

Perimeter of the second garden = 2 * (Length + Width) 600 = 2 * (Length + 60) 300 = Length + 60 Length = 300 - 60 Length = 240 meters

Therefore, the length of the second garden is 240 meters.

Answer

The length of the second garden is 240 meters.
