B: 6 + 7 = 13. Same thing as option A
C: 7 + 2 = 9. 9 is less than 13 so not the answer.
D: 8 + 8 = 16. 16 is greater than 13 so D is the correct answer.

The two other possible length of a triangle with one side as 13 cm are 8 cm and 9cm.
Triangles are plane figure with three straight sides and three angles. The sum of angles of a triangle is 180 degrees.
The triangle inequality theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.
Therefore, a triangle with sides x, y and z follows the following rule;
Since Chang know one side of the triangle, the two other possible length are as follows;
