You can put this solution on YOUR website!
First, the area of 1 square tile is 25cmx25cm=625sq cm.
\n" ); document.write( "Since you need 240 tiles to cover the whole rectangular floor, you'll have the area covered likewise. So, total 240 tiles times each area of 625sq.cm per tile = 150,000sq cm. = 15 sq.meter (take note 1 sq meter= 10,000 sq cm). \r
\n" ); document.write( "\n" ); document.write( "Therefore, to get the width we'll go to the Area(A) of rectangle=(Length)(Width)
\n" ); document.write( "15 sq m.= (5m)(W)
\n" ); document.write( "W= 3 meters.
