The perimeter of a rectangle is 34 feet and the area measures 60 square feet.
What are the length and width of the rectangle?
(Hint: Use the equations :
perimeter = times the sum of the length and the width
area = length times width)

94

2(l+w) = 34
l+w = 17 ,#1
lw = 60 , #2
from #1, w = 17l
in #2
l(17l) = 60
l^2 + 17l  60 = 0
l^2  17l + 60 = 0
(l5)(l12) = 0
so l=5 or l=12
if l=5 then w = 12
if l=12 then w = 5
The rectangle is 5 by 12 
If perimeter of garden is 2 meter mote then eight times the width of the rectangle garden. Find dimension of the garden.
