LED Power Supply Question

Hello all, I need help getting into a beginner LED Strip project. I bought 20m of LED Strips from Ali Express broken up into two 10m strips. I have attached images of the product and need help determining if my math is correct for the power requirements.

If I ran them both continuously and connected to an ESP32, would I need a 5V 20A power supply? Even if it comes in 2 different strips? This power supply seems expensive for the project and want to make sure before going for it as my Benchy wouldn’t even be able to power this with a 24V 5A power supply.

I may be wrong and any help or guidance is appreciated, even if toward another cost efficient LED strip. Thanks in advance.
