Question

What is the length of line segment EF?

Answer 1

The answer to this problem is...3.6

Answer 2

Answer:

EF = 3.6 is the answer.

Step-by-step explanation:

In the given picture coordinates of the endpoints of EF has been given and we have to calculate the length of the segment EF.

As we know when coordinates of two points are given and we have to calculate the distance between them we use the formula

Distance EF = √[(x - x')²+(y - y')²]

Here (x, y) and (x', y') are (-3, 1) and (-1, -2).

So distance EF = √(-3+1)²+(1+2)² =√(-2)²+(3)² = √(4 + 9) = √13

EF = 3.60

So the answer is 3.6
