Review on 🚣 STIVIN Adjustable Kayak Paddle 4-Piece Aluminum Shaft with Floating PP Blade, Free Leash, Comfort Non-Slip Grip, 91.7-inch Lightweight Paddles for Kayaking, Fishing, Canoeing, Touring, Recreation - Available in 5 Colors by Unm Weil

They are very well made and I love that they break into 4 pieces (blades detach from shaft) making them super easy to use are to be packed. But I sent them back because they were too short for our boat. We have a very wide inflatable tandem kayak and they hit the tubes as you paddle and pour water into the boat as you had to hold them over to change sides. They measure 91 1/2 inches or about 230 cm, this is how the rudders are measured. The correct length depends on the height of the rower and the width of the boat, this is given in the tables. For our boat, the recommended width is 39 inches, 250 cm, which is 7 inches more than yours. These were good paddles and very reasonably priced. If your size fits, they would be a great purchase.
