Asquare playground is surrounded by a sidewalk on all sides. the sidewalk is 2n+3 yards long on each side of the park. the sidewalk is 0.5 yard wide. what is the perimeter of the playground?

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).
