If wall-to-wall carpeting is installed in a room 21 ft long and 17 ft wide and the edges of the carpet are held down by tack strips, the feet of tack-strip material needed are 76 ft calculated by determining the perimeter of the rectangle room.
Tack strips are thin pieces of wood studded with nails or tacks in the installation of carpets. These thin strips are placed along all the edges of the carpet. In order to determine the length of the tack strips needed to hold the wall to wall carpeting installed in a rectangular room of 21 ft by 17 ft. The formula of the perimeter of a rectangle is:
P = 2 (length + width)
P = 2 (21 + 17)
P = 2 (38)
P = 76 ft
Hence, the feet of tack-strip material needed are 76 ft.
