Agroup of 841 square tiles are arranged as a large square on a wall. how many tiles are on each row

Each row will have 29 tiles.

Step-by-step 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.

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
