Question

Кусок проволоки согнули так что получили квадратную рамку со стороной 7 см.Можно ли из этого куска проволоки сделать рамку треугольной формы со стороной 9 см. Закрась рамку с правильным ответом ДА или НЕТ и запиши неравенство которое этот ответ подтвердит.

Answer 1

НЕТ

7 х 4 не равно 9 х 3, т.к.7х4=28, а 3х9=27

Answer 2

Can a triangular frame be made from a piece of wire that has been bent into a square frame?

To determine if a triangular frame can be made from a piece of wire that has been bent into a square frame, we need to compare the lengths of the sides of the square frame and the desired triangular frame.

The square frame has sides measuring 7 cm each The desired triangular frame has sides measuring 9 cm each.

To form a triangle, the sum of the lengths of any two sides must be greater than the length of the remaining side. This can be expressed as an inequality:

a + b > c

where a, b, and c are the lengths of the sides of the triangle.

In this case, if we let a, b, and c represent the lengths of the sides of the triangular frame, we have:

a + b > c

Substituting the given values, we have:

7 + 7 > 9

Simplifying the inequality, we get:

14 > 9

Since the inequality is true, it is possible to form a triangular frame with side lengths of 9 cm using the piece of wire that has been bent into a square frame.

Therefore, the answer is YES, a triangular frame can be made from the piece of wire, and the inequality that confirms this is 14 > 9.

Please note that the lengths of the sides of the square frame and the desired triangular frame were provided in the question, and the inequality was derived based on the triangle inequality theorem.
