Ответ:
The perimeter of the polygon is 22.
Step-by-step explanation:
Let , , and the vertices of the polygon. From Geometry we know that number of side of polygons equals their number of vertices, then we notice that a quadrilateral is here. In addition, we conclude that such quadrilateral is a rectangle:
1)
2)
3)
4)
Hence, we find that and .
Then we find all lengths of the rectangle by Pythagorean Theorem:
By Geometry, we conclude that and .
Then, the perimeter of the rectangle (), dimensionless, is defined by the following formula:
(Eq. 1)
Where:
- Shortest length, dimensionless.
- Longest length, dimensionless.
If we know that and , then the perimeter of the rectangle is:
The perimeter of the polygon is 22.
