Tim has a rose garden that is three times as long as it's wide. the total length around the garden is 80 feet. tim wants to line the exterior of the garden with paver stones. each paver stone is 2 feet by 2 feet in area.
1) area of the rose garden
2) number of paver stones needed to completely like the garden exterior.
2(w + 3w) = 80
w = 10
The garden is 10x30
Now you can find the area, and of course, the number of pavers. Don't forget the corners.
