The perimeter is:
P = 2x + 2y = 80
The area is:
A = x * y
The area as a function of a variable is:
A (x) = x * (40-x)
Rewriting we have:
A (x) = 40x-x ^ 2
We derive the function:
A '(x) = 40-2x
We equal zero and clear x:
40-2x = 0
2x = 40
x = 40/2
x = 20 feet
The other dimension is:
y = 40 - x
y = 40 - 20
y = 20 feet
The area will be:
A = x * y
A = 20 * 20
A = 400 feet ^ 2
Answer:
The dimensions are:
x = 20 feet
y = 20 feet
The area is:
A = 400 feet ^ 2
Answer:
so what i have to do
Step-by-step explanation:
17-2(6-4)(7-3)-7
17-2(2)(4)-7
17-2(8)-7
17-16-7
1-7
-6
40.0*10 is the answer
actually it is 400 but u want in decimal so it is 40.0*10
If you could put more info ab this then i would understand what u want me to put
