Question

Прямоугольника в 3 раза больше ширины Найдите длину и ширину прямоугольника если его периметр равен 48 длина прямоугольника в 3 раза больше ширины найди длину и ширину прямоугольника если его периметр равен 48

Answer 1

Ширина х, длина 3х.
По условию: х+х+3х+3х=48,
8х=48,
х=48/8=6,
ширина 6,
длина 3·6=18.

Answer 2

Problem Statement

We are given a rectangle with a length that is 3 times its width. The perimeter of the rectangle is 48. We need to find the length and width of the rectangle.

Solution

Let's assume the width of the rectangle is w. According to the problem statement, the length of the rectangle is 3 times the width, so the length can be represented as 3w.

The perimeter of a rectangle is given by the formula: P = 2 * (length + width).

Substituting the values of length and width into the formula, we get:

48 = 2 * (3w + w)

Simplifying the equation, we have:

48 = 2 * (4w)

Dividing both sides of the equation by 2, we get:

24 = 4w

Dividing both sides of the equation by 4, we get:

6 = w

Therefore, the width of the rectangle is 6.

To find the length, we substitute the value of the width back into the equation for the length:

length = 3w = 3 * 6 = 18

So, the length of the rectangle is 18.

Therefore, the width of the rectangle is 6 and the length is 18.

Answer

The width of the rectangle is 6 and the length is 18.
