How can I repair notch in bathroom vanity drawer?

[diy_vvv]

We recently installed a new bathroom vanity, but had to cut out this notch out of the bottom drawer to account for the floor pipe. 
I’d like to fix the notch with something similar to the top drawer, photo below:

I’m not sure the name of this material or if it would work for a rectangle shape. Is this possible? 
And if not, what would I need to use instead? 

I’d like the least hideous solution possible please 😂.
