Question

1800m of fencing is available to fence 6 identical pig pens as shown. if the area enclosed is to be a maximum, what is the shape of each pen?

Answer 1

do you have the options

Answer 2

The questions are :
a) explain why 9x + 8y = 1800
b)Show that the total area of each pen is given by A= -9/8x^2 + 225x m^2

Answer 3

Quadratic
functions

Answer 4

c) if the area enclosed is to be a maximum, what is the shape of each pen?

Answer 5

the shape would be the rectangle

Answer 6

let length of each pen be x and width be y

then area of the whole = 3x * 2y

length of perimeter = 3x + 3x + 2y + 2y = 6x + 4y = 1800

is this the setup?

you say in for question 'as shown' but there is no diagram
