Ineed using the distance formula to find the perimeter of a parallelogram jklm

let's first notice the distance of LM, is a vertical line, so we can just do a plain subtraction, -1.6 -(-0.4) => -1.6 +0.4 => -1.2 and the distance is just |-1.2| or 1.2.

let's check KJ, another vertica line, -1.7 - (-0.5) => -1.7 + 0.5 => -1.2 => |-1.2| = > 1.2.

so LM = KJ, and both are vertical, meaning we have a parallelogram, which means KL = JM.

so let's just find say... KL and  her twin will be the same.

i think the answer is b.

step-by-step explanation:

not 100% sure though.
