(teaser) the lengths of all sides of a triangle are integers when measured in decimeters. one of the sides has length of 1 dm and another of 3 dm. find the perimeter of the triangle.

7 dm

Step-by-step explanation:

One side is 1 dm while the other is 3 dm, so first you should add 1 and 3 together, and you get 4. you know that the answer has to be an integer. if this is an isosceles triangle then the last side has to be either 1 or 3. the last step is to add all three sides together.

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.
