Question

Длина прямоугольника 16 см, ширина - 5 cm Стороны этого прямоугольника уменьшили на 5 ст. Найди периметр полученного прямо- угольника. плз с условием​

Answer 1

Ответ:

1)16-5=11(см.)-уменшенная длина

2)5-5=0(см.)-уменшенная ширина

3)Р=2×(11+0)=2×11=22(см.)-периметр уменьшинного прямоугольніка

Answer 2

Problem Analysis

We are given a rectangle with a length of 16 cm and a width of 5 cm. The sides of this rectangle are reduced by 5 cm. We need to find the perimeter of the resulting rectangle.

Solution

To find the perimeter of a rectangle, we need to add the lengths of all four sides.

Let's calculate the lengths of the sides of the resulting rectangle after reducing each side by 5 cm.

The length of the resulting rectangle will be 16 cm - 5 cm = 11 cm. The width of the resulting rectangle will be 5 cm - 5 cm = 0 cm.

Since the width is reduced to 0 cm, we can consider it as a line segment with no length. Therefore, we only need to consider the length of the resulting rectangle.

The perimeter of the resulting rectangle is equal to the sum of the lengths of its sides, which is 11 cm + 11 cm + 0 cm + 0 cm = 22 cm.

So, the perimeter of the resulting rectangle is 22 cm.

Conclusion

The perimeter of the resulting rectangle, after reducing each side by 5 cm, is 22 cm.
