A farmer decides to enclose a rectangular garden, using the side of a barn as one side of the rectangle. What is the maximum area that the farmer can enclose with 80 feet of fence? What should the dimensions of the garden be to give the area?
Answers
max area is if the sides are as equal as possible
so he should try to make a square (ideal is a circle, but barn walls are normally straight)
squaer perimiter=4 times legnth of 1 side
perimiter=amount of fencing=80
80=4s
divide 4
20=s
one sides=20
area=legnth times width
in squaer, legnth=width
20=legnth
20=width
area=20 times 20=400
dimetions are 20ft by 20ft to give 400ft^2
(fun fact, if it were a circle, the area would be about 509.5ft^2)
answer is 20ft by 20ft and area=400ft^2

Final answer:
To evaluate -2 + (-1/3), subtract -1/3 from -2, which simplifies to -7/3.
Explanation:
To evaluate -2 + (-1/3), we need to add the two numbers together. When adding negative numbers, we can think of it as subtracting the numbers.
- So, -2 + (-1/3) is the same as -2 - 1/3. To subtract fractions, we need to have a common denominator.
- The common denominator of 2 and 3 is 6, so -2 - 1/3 is equal to -12/6 - 2/6.
- Subtracting -12/6 - 2/6 gives us -14/6. But we can simplify this fraction by dividing both the numerator and the denominator by their greatest common factor, which is 2. So, -14/6 simplifies to -7/3.
