The perimeter will be:
P = 2x + y
100 = 2x + y
The area is:
A = x * y
We write the area as a function of x:
A (x) = x * (100-2x)
Rewriting:
A (x) = 100x - 2x ^ 2
We derive:
A '(x) = 100 - 4x
We equal zero and clear x:
0 = 100 - 4x
4x = 100
x = 25 feet
The other dimension is:
y = 100-2x
y = 100-2 (25)
y = 100-50
y = 50 feet
The area will be:
A = (25) * (50)
A = 1250 feet ^ 2
Answer:
the maximum area that the farmer can enclose with 100 ft of fence is:
A = 1250 feet ^ 2
The dimensions of the garden to give this area should be:
x = 25 feet
y = 50 feet
Answer:
15 cubic meters
Step-by-step explanation:
I think your question missed key information, allow me to add in and hope it will fit the orginal one.
Please have a look at the attached photo
My answer:
Given the information in the photo, we know that:
- The height of the rectangular prism is: 1 m
- The width of the rectangular prism : 2 m
- The legnth of the rectangular prism : 4 m
=> The volume of the rectangular prism is:
V = the height * the length * The width
<=> V = 1*2*4
<=> V = 8 cubic meters
Given the information in the photo, we know that:
- The width of the triangular prism : 2 m
- The height of the is: 1 m
- The legnth of the triangular prism is: 3.5 m
=> The volume of the triangular prism is:
V = the height * the length * the width
<=> V = 1*2*3.5
<=> V = 7 cubic meters
=> the volume of the ramp is: 8 + 7 = 15 cubic meters
