A circle is inscribed in the quadrilateral AD = 18 cm, angle B = 90 °, AC = CD = 15 cm Find the perimeter of the quadrilateral.
In order to solve this problem, you need to know the properties of the quadrilateral and draw a picture to facilitate understanding of the situation.
If a circle is inscribed in a quadrilateral, then the sums of the opposite sides are equal. AB + CD = BC + AD. From this we learned all sides of this figure. To find the perimeter, all sides must be folded. P = 36 + 30 = 66 cm.
Therefore, our answer is 66 cm.
