The answer is: " <span>4 cos² Θ " .

(cos Θ − cos Θ)² + (cos Θ + cos Θ)²
= 0² + (cos Θ + cos Θ)² ;
= 0 + (2 cos Θ)² = (2 cos Θ)(2 cos Θ) ;
= 4 (cos Θ)² = 4 cos² Θ .

Answer:
The answer is below
Step-by-step explanation:
a) Let the width be represented as w and the length be represented as l.
The perimeter of the sand box = 2(l + w)
Since there is 400 feet of material for the sides of the sandbox, hence:
400 = 2(l + w)
200 = l + w
l = 200 - w
The area (A) is:
A = length * width
A = (200 - w) * w
A(w) = 200w - w²
b) The maximum area is at A'(w) = 0. Hence:
A'(w) = 200 - 2w
200 - 2w = 0
2w = 200
w = 100 feet.
l = 200 - w = 200 - 100
l = 100 feet.
Area = length * width = 100 * 100 = 10000 feet²
The maximum area of the sandbox is 10000 feet², with a length of 100 feet and width of 100 feet.
