Question

Triangle ABC is defined by the points A (3, 2),

B (3, 4), and C (6, 3). Find the perimeter of the
triangle. Round to two decimal places.

Answer 1

8.32

Explanation:

We can find the perimeter by summing up the lengths AB,BC and AC

Now let's find the individual lengths aforementioned.

|AB|=√(3-3)²+(2-4)²

=√4

|AB|=2

|BC|=√(3-6)²+(4-3)²

=√9+1

|BC|=3.16

|AC|=√(3-6)²+(2-3)²

=√9+1

|AC|=3.16

Now the individual lengths have been found so perimeter=2+3.16+3.16=8.32(to two decimal places)
