All sides of quadrilateral ABCD are tangent P.
What is the perimeter of the quadrilateral below?

P = 11.1 + 11.1 +11.1 +11.1 = 44.4

Step-by-step explanation:

P = 11.1 + 11.1 +11.1 +11.1 = 44.4

P = a + b + c + d. A quadrilateral with four right angles and all four sides of equal length. (all four angles are therefore right angles). a = c, b = d.

= 44.4

Perimeter of a circle with vortex at center point, (4 triangles are created we use the radius that also equals the perimeter)

P = r + r + r + r. A circle with four right angle triangles from center point and all four dividing lines are of equal length to radius. (all four angles are therefore right angles). a = c,  b = d.  as new lines within the circle. = 44.4
