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

Plug in 49 for area and solve for 's'

Take square root on both sides
s= 7
side of the square = 7 inches
