Answer:
option A.
Step-by-step explanation:
To solve this, we need to use the following exponent rules:
Quotient rule: (a^n)/(a^m) = a^(n-m)
Power rule: (a^n)^m = a^nm
Power of a product rule: (ab)^n = (a^n)(b^n)
Then, we have the following expressions:
So the correct result is option A.
Answer:
Length = 29 m
Width = 29 m
Step-by-step explanation:
Let x and y be the length and width of the rectangle, respectively.
The area and perimeter are given by:
Rewriting the area as a function of x:
The value of x for which the derivate of the area function is zero, is the length that maximizes the area:
The value of y is:
Length = 29 m
Width = 29 m
