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>
