How to find the permimeter of triangle abc with the vertices of a(1,1) b(7,1) c(1,9)

Perimeter of the triangle=24 units

Step-by-step explanation:

The given vertices of the triangle ABC are A(1,1), B(7,1) and C(1,9).In order to fin the perimeter, we need to find the lengths of the triangle.

Thus, AB=,

BC= and

AC=

Now, Perimeter of the triangle= Sum of all the sides

=AB+BC+AC

=6+10+8

=24 units.

Thus, Perimeter of the triangle=24 units
