rob is finishing a floor with square tiles.Each tile has an area of 412 cm squared .Estimate the length of the side of each tile .

The area of a square is just = (side length)²

So we have.........

412cm² = s²

To find the side length, we would take the square root of 412

But, the square root of 412 must be between 20 and 21, because 20² = 400 and 21² = 441

So the side length estimate is between 20 and 21 cm in length

you need to find the square root of 412.

The square root of 412 is 20.297783130184.
