Thank you for the opportunity to help you with your question!

Edge length of table,a = 20 in

Area of side of table = a^2 = 20^2 = 400 in^2

Edge length of tile,a = 5 in

Area of tile = a^2 = 5^2 = 25 in^2

Number of tiles needed on one side 

= Area of side of table / Area of tile

= 400/25

=  16

Number of tiles needed for top and 4 sides of the table

= (1 + 4)*16

= 5*16

= 80 tiles

Please let me know if you need any clarification. I'm always happy to answer your questions.
