Question

Начертить квадрат площадью 400 мм2 заштриховать 3\4 его площади.

Answer 1

400мм2=4см2
Начерти квадрат со стороной 2 см
Раздели квадрат каждую сторону поровну и соедини точки. Заштрихуй три квадрата

Answer 2

400х3/4=300 мм2 - 3/4 площади.

Answer 3

Drawing a Square with Shaded Area

To draw a square with an area of 400 mm^2 and shade 3/4 of its area, we can start by calculating the side length of the square using the formula for the area of a square: Area = side length * side length.

The formula for the area of a square is: Area = side length * side length

To find the side length of the square, we can rearrange the formula as: side length = √(Area)

Substituting the given area of 400 mm^2 into the formula: side length = √(400 mm^2) side length = 20 mm

Now that we have the side length of the square, we can draw a square with each side measuring 20 mm.

Next, to shade 3/4 of the square's area, we can calculate the area to be shaded: Shaded area = 3/4 * 400 mm^2 Shaded area = 300 mm^2

We can then shade an area of 300 mm^2 within the square to represent 3/4 of its total area.

This approach ensures that the square is accurately drawn with the specified shaded area.
