Siri is lining a square tree with 1 in.² tiles the side length of the tree is 9 inches how many tiles does Sarah need
a square tree? Do you mean tray?
In any case, it will clearly take 9x9 tiles.
I wonder if her square tree also has square roots.
To calculate the number of tiles Sarah needs to line a square tree with 1 in² tiles, we need to determine the total area of the tree and divide it by the area of each tile.
In this case, the tree is a square with a side length of 9 inches. To find the area of the tree, we square the length by multiplying it by itself:
Area of the tree = side length * side length = 9 inches * 9 inches = 81 square inches.
Since each tile has an area of 1 in², we can find the number of tiles by dividing the total area of the tree by the area of each tile:
Number of tiles = Area of the tree / Area of each tile = 81 square inches / 1 in² = 81 tiles.
Therefore, Sarah would need 81 tiles to line the square tree.
