An ecology center wants to set up an experimental garden using 300 m of fencing to enclose a rectangular area of 5000m2. Find the dimensions of the garden.
-----------------
Equations:
LW = 5000
2(L+W) = 300
-------------------
L+W = 150
LW = 5000
-------------------
Solve by substitution:
L = 150-W
---------------
(150-W)W = 3000
-W^2 + 150W - 3000 = 0
W^2 - 150W + 3000 = 0
---
I graphed it and found W = 126.23
Then L = 23.77
