The perimeter of the triangle in the image measures 19.8 units.
<h3>
How to get the perimeter of the triangle?</h3>
Remember that the distance between two points (a, b) and (c, d) is:
distance = √( (a - c)^2 + (b - d)^2)
In this case, the vertices of the triangle are:
(0, 1), (4, -2) and (-5, -2)
The distance between each pair of vertices is:
d₁ = √( (0 - 4)^2 + (1 + 2)^2) = 5
d₂ = √( (4 + 5)^2 + (-2 + 2)^2) = 9
d₃ = √( (-5 - 0)^2 + (-2 - 1)^2) = 5.8
Then the perimeter of the triangle is:
P = 5 + 9 + 5.8 = 19.8
