Question

Длина прямоугольника 24 см. Длина в 4 раза больше ширины.Найди периметр и площадь.

Answer 1

24*4=96
(24*2)+(96*2)=240-периметр
24*96=2304-площадь
Вроде так;)

Answer 2

А=24
б=24/4=6
P=2*(a+b)
S=ab
P=2* (24+6)=60см
S=24*6=144 см²

Answer 3

Problem Analysis

We are given that the length of a rectangle is 24 cm and that the length is 4 times the width. We need to find the perimeter and area of the rectangle.

Solution

Let's denote the width of the rectangle as w. According to the problem, the length is 4 times the width, so we have:

Length = 4w

We are also given that the length is 24 cm, so we can write:

4w = 24

To find the width, we can divide both sides of the equation by 4:

w = 24 / 4 = 6

Now that we know the width, we can calculate the perimeter and area of the rectangle.

Perimeter

The perimeter of a rectangle is given by the formula:

Perimeter = 2(length + width)

Substituting the values we know:

Perimeter = 2(24 + 6) = 2(30) = 60 cm

Therefore, the perimeter of the rectangle is 60 cm.

Area

The area of a rectangle is given by the formula:

Area = length * width

Substituting the values we know:

Area = 24 * 6 = 144 cm^2

Therefore, the area of the rectangle is 144 cm^2.

Summary

Given that the length of the rectangle is 24 cm and the length is 4 times the width, we can calculate the perimeter and area of the rectangle. The width of the rectangle is 6 cm, the perimeter is 60 cm, and the area is 144 cm^2.
