Answer:
The dimensions are 50 and 100 square foot
Step-by-step explanation:
Let x = length of fenced side parallel to the side that borders the playground
y = length of each of the other two fenced sides
Then, x + 2y = 200
<=> x = 200-2y
The Area = xy = y(200-2y)
The dimensions of the playground that will minimize the homeowner's total cost for materials when the area of the playground is maximum. He can cover more area but with the same cost.
The graph of the area function is a parabola opening downward.
The maximum area occurs when y = -200/[2(-2)] = 50
=> x = 100
So the dimensions are 50 and 100 square foot
I don’t know but I need the Points sorry for you
The expression can be simplified to a polynomial of degree 2.

How to simplify the expression?</h3>
Here we have the expression:

We can directly simplify this by taking the variable as common factor:

This is a polynomial, as you can see, the maximum exponent is 2, so the degree of the polynomial is 2.
