Answer:
Step-by-step explanation:
Perimeter of rectangle = 208 m
2*(l + w) = 208 {divide both sides by 2}
l +w = 208/2
l +w = 104
l = 104 - w
Area of rectangle = 2415 square meters
l*w = 2415
Substitute l = 104 - w in the above equation,
(104 - w ) *w = 2415
104w - w² = 2415
0 = 2415 - 104w + w²
w² - 104w + 2415 = 0
Sum = -104
Product = 2415
Factors = (-69) , (-35)
w² - 35w - 69w + (-69)*(-35) = 0
w(w - 35) - 69(w - 35) = 0
(w -35)(w -69)
w - 35 = 0 ; w -69 = 0
w = 35 ; w = 69
The dimensions of the building: 35 , 69
We want to find out how much it costs for each pound of feed
For chicken feed 12 divided by 8.40
$1.43 for 1 pound of chicken feed
For goat feed 75 divided by 60
$1.25 for 1 pound of goat feed
For dog feed 50 divided by 37.50
$1.33 for 1 pound of dog feed
For pig feed 80 divided by 62.80
$1.27 for 1 pound of pig feed
When reviewing all the answers per pound for feed, chicken feed is the most expensive per pound.
Hope this helps:)
