Question

длина прямоугольника в 3 раза большеего ширины а периметр равен 32 найдите длину и ширину прямогльника

Answer 1

Пусть х-ширина прямоугольника,тогда 3х-длина прямоугольника. Периметр прямоугольника равен 32 или 2(3х+х) 2(3х+х)=32 2*4х=32 8х=32 Х=32:8 Х=4 Ширина=4 Длина=4*3=12.

Answer 2

Finding the Length and Width of a Rectangle

To find the length and width of a rectangle when the length is three times the width and the perimeter is 32, we can use the following steps:

1. Set up the equations: Let's denote the width of the rectangle as w and the length as 3w (since the length is three times the width). The perimeter of a rectangle is given by the formula: \[ \text{Perimeter} = 2 \times (\text{length} + \text{width}) \] Given that the perimeter is 32, we can write the equation: \[ 2 \times (3w + w) = 32 \]

2. Solve for the width: Solving the equation for the width will give us the value of w.

3. Calculate the length: Once we have the value of w, we can find the length by multiplying it by 3.

Let's proceed with solving the equation to find the width and then calculate the length.
