Step-by-step explanation:
- m∠5 ≅ m∠4; Angle Correspondence Theorem
- m∠5 ≅ m∠1; Alternate Interior Angles Theorem
- m∠6 ≅ m∠2; Alternate Exterior Angles Theorem
- 180° = m∠2 + m∠1; Definition of Linear Pair [Supplementary Angles]

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 .
