Question

Diego has 49 square inch tiles. He wants to use to make a square mosaic. How long can each side of the mosaic be?

Answer 1

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

$Area = s^2$

Plug in 49 for area  and solve for 's'

$49 = s^2$

Take square root on both sides

s= 7

side of the square = 7 inches
