Answer:
93.75 feet and 187.5 feet
Step-by-step explanation:
Let the width of the rectangular area be x feet and the length be y feet. A farmer with 750 feet of fencing wants to enclose a rectangular area and then divide it into three pens with fencing parallel to one side of the rectangle. So, there will be 4 widths and 2 lengths, thus
Find the area:
Find the derivative:
Equate it to 0:
Let X be birds = ?
Y be beasts = ?
heads = 60
feet = 200
feet of birds = 2
feet of beast = 4
From data we come to know that
total animals = X+Y=60____1
total feet = 200 = 2X + 4Y_____2
from equation 1 X= 60-Y
put this value of X in equation 2
2(60-Y) + 4Y = 200
120 - 2Y + 4Y = 200
2Y= 200 - 120
2Y = 80
Y = 40
Now from value of Y we can calculate X
X + Y =60
X + 40 = 60
Or X = 20
The number of beasts is equal to 40 where as number of birds is equal to 20.
Y - 9 = -1/4 ( x + 2)

Answer: 840
Step-by-step explanation: 50% is half. All I did was add 420 two time since 420 is half of what this person has to spend.
