Answer:
A can paint in 3days and B in 6 days
Step-by-step explanation:
From the question we were told
Person A can paint the neighbors house 2 times as fast as Person B
Let A only paint the neighbors house in X days
Let B only paint the neighbors house in 2X days
If we express the given information from the question in terms of fraction we have,
1/X + 1/2X = 1/2
3/2X = 1/2
if we cross multiply we have
6= 2X
X= 6/2
X= 3
Then A can paint the house in 3 days and B in 2(3)= 6days.

The triangle is shown in the attached figure, and have three vertices: 
, 
and 
.
Each vertice represents a point in the cartesian plane and the length of each side of the triangle is the modulus of each vector.
In this sense, the modulus 
is calculated as shown:
Hence, for each vector:
Now, the perimeter of a triangle is the sum of its three sides:
Finally:
