Question

Начерти квадрат со стороной 7 см.Закрась 1/7 площади квадрата.Сколько квадратных см. ты закрасил? Как это начертить?

Answer 1

Рисуешь квадрат шириной 7см и длиной 7см)
площадь квадрата вычисляется по формуле s = a^2(сторона в квадрате)
7*7 = 49см^2
теперь нужно разделить площадь на семь частей, чтобы получить искомое число
49:7 = 7см^2
ответ: семь

Answer 2

Drawing a Square with Side Length 7 cm and Shading 1/7 of Its Area

To draw a square with a side length of 7 cm and then shade 1/7 of its area, follow these steps:

1. Drawing the Square: - Start by drawing a straight line segment with a ruler that is 7 cm long. - Then, draw three more straight line segments, each 7 cm long, connected to the endpoints of the first line segment to form a closed shape with four equal sides.

2. Shading 1/7 of the Area: - After drawing the square, calculate the total area of the square using the formula: Area = side length * side length. - Then, shade 1/7 of the total area of the square.

Calculating the Area of the Square and Shading 1/7 of It

To calculate the area of the square with a side length of 7 cm: - Area = side length * side length - Area = 7 cm * 7 cm - Area = 49 square cm

Now, to shade 1/7 of the total area: - 1/7 of 49 square cm = (1/7) * 49 square cm - 1/7 of 49 square cm = 7 square cm

So, the area to be shaded is 7 square cm.

You can use a pencil or a marker to shade an area of 7 square cm within the square to represent shading 1/7 of its total area.
