What is the perimeter, in units, of the triangle shown on the coordinate grid? (44units

(36units

(34units

(12units

36 units

Step-by-step explanation:

Perimeter of the triangle is the total distances between the vertices which can be calculated as follows using distance formula where necessary:

Distance between (-1, -4) and (9, -4):

This can be calculated without using the distance formula.

The distance between both vertices = |9 -(-1)| = 10 units

Distance between (-1, -4) and (4, 8):

Let,

Distance between (9, -4) and (4, 8):

Let,

Perimeter = 10 + 13 + 13 = 36 units
