A rectangular room is 10 feet longer than it is wide. One-foot-by-one-foot tiles cover the entire floor. Let w represent the width (in feet) of the room. Write an expression in simplest form that represents the number of tiles along the outside of the room.

The simplest form that represents the number of tiles along the outside of the room is ()

Step-by-step explanation:

Let W be the wide of the rectangular room.

So length of the room L =(W+10) foot

Area of the rectangular room = (Length x Wide) of the room.

                                                =W x (W+10)

                                                =      

Therefore, Area of the tiles =

So, the total no of tiles required =area of the rectangular room /area of tiles.

                                                     =

                                                    =() piece

50
