Kansas state is the rectangle on the right; Kansas City is one of those weird things which exists in both Kansas and Missouri next to each other, one was named after the other. Technically one is a small suburb of the other (150k ppl vs 2m ppl) - but for pub trivia, it does exist by name as an incorporated city in the state of Kansas.
Additional fun fact, Kansas has in the past attempted to annex Kansas City, Missouri.
The metro area being split between MO and KS has also caused a race to the bottom for certain kinds of regulations and taxes because for many businesses the cost of moving between the two states was essentially moving from one side of State Line Rd to the other.
The cities also indexed their streets off of the same river, but at different places along the curving bank. As a result, traveling south in KCMO increments the street numbers, but in KCK, the numbers increment when you travel west.
For more hilarity, the cities to the south of KCK adopted the KCMO street number designations, so KCK is the odd city out.
The one on the right is Kansas. Also of note: Kansas city is one city/Metropolitan area in two states. It's just unique in that it has the same name in both states
The area around Chicago - TIL it is called "Chicagoland", can anyone comment how often that is used by people in the region? - likewise extends into multiple (more than just two) states!

Frequently, though it’s mostly informal shorthand for “the greater Chicago metropolitan area”, you probably wouldn’t say “I live in Chicagoland” unless you were intentionally being vague.
