The first steps in determining the perimeter of triangle abc are shown.

to the nearest whole unit, what is the perimeter of triangle abc?

Step-by-step explanation:

The perimeter of a triangle is the sum of the lenghts of its sides.

Given the triangle ABC , its perimeter will be:

Then, you know that the lenghts of the sids of the triangle ABC are:

Therefore, to find the perimeter of this triangle, you need to substitute these lengthts into the formula .

So, the perimeter of the triangle ABC is:

To the nearest whole unit is:

the answer is 13 cm
