Question

Начерти квадрат MNPK,длина стороны которого равна 3 см. Раздели его по линиям клеток на 9 равных частей. Найди площадь Одной такой части

Answer 1

3 в кубе = 9; 9 х 2(в 1см 2 клетки) = 18 клеток. а клетки = 0,5 см Р = 0,5 в квадрате Р = 2 (см.) Ответ: Р = 2 см

Answer 2

Drawing a Square and Dividing it into Equal Parts

To draw a square MNPK with a side length of 3 cm and divide it into 9 equal parts, follow these steps:

1. Start by drawing a straight line segment of length 3 cm. This will be one side of the square. 2. From one end of the line segment, draw another line segment perpendicular to the first one, also measuring 3 cm. This will be the second side of the square. 3. Connect the endpoints of the two line segments to form a square. Label the vertices as M, N, P, and K.

The square MNPK should now be drawn.

To divide the square into 9 equal parts, we can draw lines parallel to the sides of the square to create a grid. Each part will be a smaller square with equal side lengths.

Finding the Area of One Part

To find the area of one part, we need to determine the side length of each smaller square.

Since the original square MNPK has a side length of 3 cm, we can divide each side into 3 equal parts. This means each smaller square will have a side length of 1 cm.

To find the area of a square, we square the length of one side. Therefore, the area of one part is 1 cm x 1 cm = 1 cm².

So, each of the 9 equal parts of the square MNPK has an area of 1 square centimeter.
