Question

Выйдет ли квадратная проволочная рамка со стороной 7 см из треугольной рамки, каждая сторон которой равна 9 см

Answer 1

Ответ:

нет не выйдет

Пошаговое объяснение:

Если у квадратной рамки все стороны равны 7см, тогда 7•4=28см, то есть нам нужно 28см. У нас есть треугольная рамка, каждая сторона которой равна 9см, тогда 9•3=27, следовательно, мы имеем только 27см, поэтому сделать квадратную рамку невозможно

Answer 2

Can a square wire frame with a side of 7 cm fit into a triangular frame, each side of which is 9 cm long?

To determine if a square wire frame with a side of 7 cm can fit into a triangular frame, each side of which is 9 cm long, we need to consider the dimensions and shapes of the two frames.

The area of the square wire frame can be calculated using the formula: Area = side length * side length

The area of the triangular frame can be calculated using the formula: Area = (base * height) / 2

Let's calculate the areas and compare them to see if the square wire frame can fit into the triangular frame.

The area of the square wire frame with a side of 7 cm is: Area = 7 cm * 7 cm = 49 cm²

The area of the triangular frame with each side of 9 cm can be calculated using the formula: Area = (9 cm * 9 cm * √3) / 4 ≈ 35.77 cm²

Comparing the areas, we can see that the area of the square wire frame (49 cm²) is larger than the area of the triangular frame (35.77 cm²). Therefore, it is possible for the square wire frame with a side of 7 cm to fit into the triangular frame, each side of which is 9 cm long.
