Question

площадь города имеет форму прямоугольника 55м* 48м.Вокруг площади-пешеходная зона шириной 6м, а в центре-сквер.Какую площадь занимает сквер? предложите разные способы решения.

Answer 1

55м-это длина, а 48 м. ширина их надо уменьшить на 6 м, но так как пешеходная зона вокруг города то умножаем 6 на 2.

1). 55-6*2=43м

2).48-6*2=36м

Ответ площадь сквера 43 на 36

Answer 2

Calculation of the Square's Area

To calculate the area of the square, we can use the formula: Area = length * width. In this case, the length of the square is 55 meters and the width is 48 meters. Therefore, the area of the square is:

Area = 55m * 48m = 2640 square meters.

Calculation of the Pedestrian Zone's Area

To calculate the area of the pedestrian zone, we need to subtract the area of the square from the total area of the rectangle. The pedestrian zone surrounds the square and has a width of 6 meters on all sides.

The total area of the rectangle is 55m * 48m = 2640 square meters.

The area of the square is 2640 square meters.

Therefore, the area of the pedestrian zone is:

Area of Pedestrian Zone = Total Area of Rectangle - Area of Square = 2640 square meters - 2640 square meters = 0 square meters.

Since the pedestrian zone surrounds the square completely, it does not occupy any additional area.

Different Methods of Solution

1. Method 1: Calculation using the formula: As mentioned above, we can calculate the area of the square by multiplying its length and width. Then, we can subtract the area of the square from the total area of the rectangle to find the area of the pedestrian zone.

2. Method 2: Visual representation: We can draw a diagram of the city with the given dimensions and visually calculate the area of the square and the pedestrian zone. By representing the city as a rectangle and the square as a smaller rectangle within it, we can easily determine the areas.

3. Method 3: Dividing the rectangle: We can divide the rectangle into smaller sections, including the square and the pedestrian zone. By calculating the areas of these smaller sections and subtracting the area of the square, we can find the area of the pedestrian zone.

These are just a few possible methods to solve the problem. The choice of method depends on the available information and personal preference.
