Question

Quadrilateral KLMN has vertices of K(-4,-1), L(-1,-1) M(-2,-5) and N(-4,-4) Find the length of MN

Answer 1

B

Explanation:

Answer 2

The length of MN is
`√(5)` units.

Explanation:

The given Quadrilateral KLMN has vertices at K(-4,-1), L(-1,-1) M(-2,-5) and N(-4,-4).

We use the distance formula to find the length of MN.

`|MN|=√((x_2-x_1)^2+(y_2-y_1)^2)`

We plug in the values to get

`|MN|=√((-4--2)^2+(-4--5)^2)`

`|MN|=√((-2)^2+(1)^2)`

`|MN|=√(4+1)`

`|MN|=√(5)`

The length of MN is
`√(5)` units.
