Question

How do I find the total area of three connected equally sized pens built so as to maximize the area bounded?

Answer 1

I'll be glad to help you,but there's no sides or measurement?

Answer 2

Sorry - the total amount of fencing is 240 feet

Answer 3

if the pens have equal width x, and length y, and are connected in a line, with the widths adjoining, then

6y + 4x = 240
x = (120-3y)/2

area a = 3xy
a = 3 (120-3y)/2 y
da/dy = 9(20-y)
a is max when y=20
so, x = 30
3xy = 1800 ft^2
