-- Measure the length and width of the room, in feet.-- Multiply the (length of the room) times (the width of the room), in feet.-- The answer is the number of square feet of carpet required to cover the floor of the room.

2*(length + width) = 54 feet.
Length + width = ½ perimeter, ie 42 yards or 126 feet. L = 6 W so w = 126/7 = 18 feet and length is 108 feet ie 36 yards.
If it is a square room then its perimeter is: 4*15 = 60 feet
The length is 15 feet.
Length = 38 feet Width = 19 feet Check: 2*(38+19) = 114 feet
This has multiple answers. If you divide the length, room two is 36' x 12', with perimeter of 96' and area of 432 sq. ft. If you divide the width, room two is 48' x 9', with perimeter of 114' and area of 432 sq. ft.

If the room is rectangular, the area is simply length x width. If length and width are in feet, then the result of the multiplication will be square feet.
