<PRE><B>Question 184161</B>
A farmer has 120 yards of fencing to build around a rectangular orchard. Let w be the width of the orchard. Write an equation giving the area of the orchard. Find the dimensions of the orchard when the area is 900 square yards.
---------------------------
Perimeter = 2(L + W)
120 yds = 2(L + W)
L+W = 60
L = 60-W
-------------
Area = L*W
Area = (60-W)W
Area = 60W-W^2
--------------------
900 = 60W-W^2
W^2 - 60W + 900 = 0
(W-30)(W-30) = 0
W = 30 yds (Width)
----
L = 30yds (length)
