Answer:
length = 60 foot, width = 30 foot
Step-by-step explanation:
Area of rectangular part, A = 1800 ft²
Cost of fencing three sides is $ 6 per foot and cost of one side fencing is $18 per foot.
Let the length of the rectangle is l and the width of the rectangle is W.
Area = Length x width
A = L x W
1800 = L x W ...... (1)
Total cost of fencing, C = 6 x ( L + W + L) + 18 x W
C = 6 (2L + W) + 18 W
C = 12 L + 24 W
Substitute the value of W from equation (1),
in equation (2)


Differentiate both sides with respect to L:

Put it equal to zero for maxima and minima

L = 60 foot
and W = 30 foot
So, the costing is minimum for length = 60 foot and the width = 30 foot.
Answer:
The answer is 11 5/18 because it is so easy.
Let Hannah's age be represented by h;
Since Anthony's age is a consecutive odd number age; his age is (h+2)
92=(h)(h+2)
92-2=2h
90=2h
90/2=h
45=h
If Hannah is 45 years old, Anthony is (45+2)= 47 years old
Hope I helped :)
Answer:
OKI....
Step-by-step explanation:
Sooooo......add the numbers:
it equals 71
