The area of an isosceles trapezoid ABCD is 24 cm^2, and the diameter of an inscribed circle is 4 cm. Find the perimeter of the trapezoid.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[ABCD] = 24           r = 2               Circle center => O         ∠AOD = 90º

 

AD = BC = (1/2[ABCD]) / r = 6

 

AD + BC = 12

 

AD + BC = AB + CD

 

So, the perimeter is 24 cm
