a Carper lawyer wishes to determine the cost of carpeting a rectangle room who's perimeter is 32 feet. suppose that the length of the room is 4 more feet than its width. what is the length of the room and the total cost of the carpet if it cost $18.95 per square yard
.
Let w = width
then
w+4 = length
.
2(w + w+4) = 32
2(2w+4) = 32
2w+4 = 16
2w = 12
w = 6 feet
.
Length:
w+4 = 6+4 = 10 feet (length of room)
.
area = 6*10 = 60 square feet
since there is 9square feet per square yard:
60/9 = 6.667 square yards
.
Cost:
6.667 * 18.95 = $126.33
