Question

Начерти в тетради квадрат периметр которого в 2 раза меньше периметра треугольника длина каждой стороны которого равна 8 сантиметров вычесли площадь этого квадрата в квадратных сантиметров

Answer 1

P=8*3/2=12

a=12/4=3

S=3*3=9cm²

Answer 2

Периметр треугольника равен 3 х 8 = 24 см
24 : 2 = 12 см периметр нужного квадрата
12 : 4 = 3 см сторона квадрата
чертишь квадрат, каждая сторона которого равна 3 см
3 х 3 = 9 кв.см. -площадь этого квадрата

Answer 3

Task: Drawing a Square and Calculating its Area

To solve this task, we need to draw a square in a notebook. The perimeter of this square should be half the perimeter of a triangle, where each side of the triangle is 8 centimeters long. After drawing the square, we need to calculate its area in square centimeters.

Let's break down the steps to solve this task:

1. Drawing the Square: - Start by drawing a square in your notebook. - The square should have sides of equal length. - The perimeter of this square should be half the perimeter of the triangle.

2. Calculating the Area of the Square: - To calculate the area of a square, we need to know the length of one side. - In this case, the length of each side of the square is not given directly. - However, we know that the perimeter of the square is half the perimeter of the triangle. - The perimeter of the triangle is the sum of the lengths of all three sides. - Since each side of the triangle is 8 centimeters long, the perimeter of the triangle is 8 + 8 + 8 = 24 centimeters. - Therefore, the perimeter of the square is half of 24 centimeters, which is 12 centimeters. - The perimeter of a square is the sum of all four sides, so each side of the square is 12 / 4 = 3 centimeters long.

3. Calculating the Area of the Square: - To calculate the area of a square, we need to square the length of one side. - In this case, the length of each side of the square is 3 centimeters. - Therefore, the area of the square is 3 * 3 = 9 square centimeters.

So, the area of the square is 9 square centimeters.
