Parallel to the x-axis and perpendicular to the y-axis: zero
Parallel to the y-axis and perpendicular to the x-axis: undefined
I hope that's right, that's how I remember it
Let the width =x
length = 6x
p=14x
28=14x
x=2
12000 - 2900 = 9100
9100 / 36 = 252.77.....about 253 per month
Y=4x i believe is the answer
