To find the length of KL, we need to use the distance formula which is derived from the Pythagorean theorem. The distance formula is:

d = sqrt[(x2 - x1)^2 + (y2 - y1)^2]

Here, the coordinates of K are (-1,-4) and the coordinates of L are (-4,-1).

So, substituting these values into the formula, we get:

d = sqrt[(-4 - (-1))^2 + (-1 - (-4))^2]
d = sqrt[(-3)^2 + (3)^2]
d = sqrt[9 + 9]
d = sqrt[18]

The square root of 18 is approximately 4.24.

Rounding to the nearest whole number, the length of KL is 4.
