Please read and check this document.  Your help will be appreciated


You must construct the figure above using 2600 cm of material.  (this must be
used to construct all the lines in the diagram).  What is the maximum area of
the figure?

A possible solution could be:

2X+6Y=2600
2X=2600-6Y
X=(2600-6Y)/2

A=XY
A=Y(1300-3Y)
A=1300Y-3Y2
A=-3Y2+1300Y

Formula
(-(b))/2a=

Substitution
(-(1300))/2(-3)=

Solution
-1300/-6=216.66...

Is the answer for this question 216.7 cm2?

If not please write back? 

Thanks

Alex B.
