C. 21.4 millimeters
D. 30.8 millimeters
Answers
We have to calculate the perimeter of the figure to the nearest tenth of a millimeter. This figure is made of a rectangle and a half of a circle. The first figure has the perimeter: 3 + 6 + 3 = 12 mm. The second figure has the perimeter: 2 * Pi * r / 2 = Pi * r ; and the radius : r = 6/2 = 3 mm. So Pi * 3 = 3.14 * 3 = 9.42. Fimally : 12 + 9.42 = 21.42 or 21.4 to the nearest tenth. Answer: C. 21.4 millimeters.

If the lengths of two of the sides of a triangle are 1 and 20, then the third side can be any length between 19 and 21.
It's not possible to calculate it exactly until we know more information about the triangle.
For example, if the triangle is a right triangle, then the length of the third side is
