Question

На квадратном листе бумаги сторона которого 10 см ты соединил отрезками середины каждой пары соседних сторон и по ним выполнил разрезы ножницами получилась новая фигура. Вычисли её площадь. плизз

Answer 1

Лист поделился на 4 части и получилось, что сторона маленького квадрата = 4 см
4х4= 16.

Вот.

Problem Analysis

We have a square sheet of paper with sides measuring 10 cm. The paper is divided by connecting the midpoints of each pair of adjacent sides, and then cuts are made along these lines with scissors. We need to calculate the area of the resulting figure.

Solution

To solve this problem, we can break down the steps as follows:

1. Calculate the area of the original square. 2. Calculate the area of the smaller squares formed by connecting the midpoints of each pair of adjacent sides. 3. Subtract the area of the smaller squares from the area of the original square to find the area of the resulting figure.

Let's calculate the area step by step.

Step 1: Calculate the area of the original square

The original square has sides measuring 10 cm. To calculate the area, we use the formula: Area = side length * side length. Therefore, the area of the original square is 10 cm * 10 cm = 100 cm².

Step 2: Calculate the area of the smaller squares

By connecting the midpoints of each pair of adjacent sides, we create four smaller squares within the original square. Each smaller square has sides measuring half the length of the original square, which is 5 cm. To calculate the area of each smaller square, we use the same formula: Area = side length * side length. Therefore, the area of each smaller square is 5 cm * 5 cm = 25 cm².

Step 3: Calculate the area of the resulting figure

To find the area of the resulting figure, we subtract the sum of the areas of the smaller squares from the area of the original square. The sum of the areas of the smaller squares is 4 * 25 cm² = 100 cm² (since there are four smaller squares). Therefore, the area of the resulting figure is 100 cm² - 100 cm² = 0 cm².

Answer

The area of the resulting figure is 0 cm².

Please note that the resulting figure may not have a well-defined shape, as it depends on the specific cuts made along the lines connecting the midpoints of the original square.
