Problema Solution
Dave and Jane Wells have a new rectangular drieway. The perimeter of the direveway is 168 feet. the length is 12 feet longer than three times th width. What are the dimensions of the driveway?
Answer provided by our tutors
Let the length of driveway be x feet
and width of drive way be y feet
perimeter = 2(x+y)
2(x+y) = 168
x+y = 84 ............(1)
length =width +12
x = y + 12
x - y =12 ..........(2)
adding (1) and (2)
2x = 96
x = 48 feet
y=36 feet
