Answer:
<h3>Perimeter = 8n+8 yards.</h3>
Step-by-step explanation:
We are given the length of sidewalk of each side of the park =2n+3 yards.
Also, sidewalk is 0.5 yard wide from each side.
Therefore, length of a side of the square playground would be 0.5+0.5 on each side of side walk.
Therefore, length of a side of the square playground = 2n+3 -(0.5+0.5)
= 2n+3-1 = 2n+2.
The perimeter of the square = 4(side).
<h3>Therefore, the perimeter of the square playground = 4(2n+2) = 8n+8 yards.</h3>
