Question

Four congruent triangle corners are cut off an 11 × 13 rectangle. The resulting octagon has edges of equal length, then what is its length?​

Answer 1

Answer:

The resulting octagon has edges of equal length, then its length 3cm.

Step-by-step explanation:

Step : 1   A regular octagon shape has eight equal sides and eight equal angles. All the sides are of equal length, and all the angles are of equal measure. The sum of the interior angles is 1080°, and the sum of the exterior angles is 360°. In a regular octagon, the interior angle at each vertex is 135°.

Step : 2  The octagon is a two-dimensional, 8-sided polygon, often known as an 8-gon, in plain English. All of the sides of a regular octagon will be the same length. A regular octagon has internal angles that are each 135° in length. As a result, the outside angle is calculated as 180° - 135° = 45°.

Step : 3  An irregular octagon is one in which the sides and angles do not line up. The eight sides and eight angles of an irregular octagon are therefore not equal. It has uneven sides and angles like an octagon. The sum of all interior angles, which vary in size, is always 1080 degrees.
