The area of a square carpet tile is 900 square centimeters. What is the length of one edge of the tile in centimeters

satela [25.4K]

Let the side of one edge of tile = a cm.

So area of tile = (side)^2 = $a^2$

But area of tiles = 900 square centimeter.

So $a^2 = 900$

$a = \sqrt{900}$
$= 30$

So side of one edge of tile is = 30 cm
