Perimeter is  8 + √(10) units.Step-by-step explanation:First we have to find the distance between the all the 3 points and then using the distances, we can find the sum of it, so that we will get the perimeter of the triangle.The points are L(2,4) , M(-2,1) and N(-1,4) Distance between the points can be found as, √((x₂-x₁)² + (y₂-y₁)²)Plugin the values in the given point, we will get LM as, LM = √((-2-2)² + (1-4)²)     = √((-4)² + (-3)²)    = √(16 + 9) = √(25) = 5 units.MN = √((-1-(-2))² + (4-1)²)      = √((-1+2))² + (4-1)²)     = √((1))² + (3)²)     = √(1 + 9) = √(10)  NL = √((2-(-1))² + (4-4)²)       = √((3)² + 0²) = √(9) = 3 unitsPerimeter = LM + MN + NL = 5+ √(10) + 3 = 8 + √(10) units.
