Answer:
Each row will have 29 tiles.
Explanation:
Number of square tiles given = 841
These tiles are to be arranged as a large square on a wall.
Let each row of the wall contains T tiles then area will be covered by the number of tiles = T×T
So the expression will be T² = 841
T = √841
T = √(29×29)
T = 29
Therefore, each row will have 29 tiles.
