Answer: It  can be calculated by using the formula of perimeter and by adding four sides

1) Perimeter= 2(L+B)= 8n+12

2) Perimeter= L+L+L+L= 4L= 8n+12

Step-by-step explanation:

As it is a square playground all its sides are equal

Perimeter of the sidewalk = 2(L+B)= 2(2n+3+0.5)= 2(2n+3.5)= 4n+7

Perimeter of the square playground= <em><u>2(L+B)</u></em>= 2(2n+3+2n+3)

<em>2(4n+6)= 8n+12-------------------------A</em>

Perimeter of the square playground<u><em>= L+L+L+L=4L</em></u>  42n+3+2n+3+2n+3+2n+3=<u><em>4(2n+3)= 8n+12------------------------B</em></u>
