a room is 7m 20 cm long and 5m 20cm broad. if square tiles have to be laid in such a way that an exact number of tiles fit in and no tile has to be cut, what is the greatest length of the side of sqare tiles.
hi,
lets convert all the the units of mesurements into the same unit.
so length of room = 700 cm + 20 cm = 720 cm
breadth of room = 500cm + 20 cm = 520 cm.
area of the room will be (720 x 520)cm the room should be a rectangle.
= 374400 cm or 3744 m.
