Answer:
76 more tiles are needed to complete the patio.
Step-by-step explanation:
Allie is building a patio. The patio will have 8 tiles in each of 13 rows.
Total tiles needed = [tex]8\times13=104[/tex]
She has already built the center section with 4 tiles in each of 7 rows.
Tiles used = [tex]4\times7=28[/tex]
So, more tiles needed = [tex]104-28=76[/tex]
Therefore, 76 more tiles are needed to complete the patio.
