Answer:
B) 5 + 3√5 units
Step-by-step explanation:
The length of ZX is 2√5 units. What is the perimeter of triangle XYZ?
A) 5 +√3 + 2 √5 units
B) 5 + 3√5 units
C) 5 + √6 + 2√5 units
D) 10 + 2√5 units
From the diagram attached, point X is at (-1, 4), Y(3, 1), Z(1, 0).
The distance between two point
The lengths of the sides of the triangle are:
The perimeter of the triangle is the sum of all the sides, i.e.
Perimeter = |XY| + |YZ| + |XZ| = 5 + 2√5 + √5 = 5 + 3√5
