Answer:

side of the mosaic  = 7 inches

Step-by-step explanation:

Diego has 49 square inch tiles. He wants to use to make a square mosaic.

Area of the tile = 49 square inches

We know , area of the square = s^2

where 's' is the side of the square

[tex]Area = s^2[/tex]

Plug in 49 for area  and solve for 's'

[tex]49 = s^2[/tex]

Take square root on both sides

s= 7

side of the square = 7 inches
