Answer:
a) The polynomial is equivalent to 
, and the side length of the playground is 
feet.
b) The perimeter of the playground, measured in feet, is 
.
Step-by-step explanation:
a) By Geometry, we know that area of the square is equal to the square of the side length. If 
is the area of the square, then must be a perfect square trinomial, that is:
(1)
Then, we must observe the following properties:
(2)
(3)
Therefore, the polynomial is equivalent to , and the side length of the playground is feet.
b) The perimeter of a square equals four times the side length. That is:
The perimeter of the playground, measured in feet, is .

Answer:
30 percent
Step-by-step explanation:
15 + 13 + 4 + 10 + 8 = 50
15/50 = 30/100
You would use the formula for the area of a rectangle. A=l(w). The length would be 2w+3. the width is 5.
