Asquare playground is surrounded by a sidewalk on all sides. the sidewalk is 2n+3 yards along each side. the sidewalk is 0.5 yard wide. what is the perimeter of the playground? write two equivalent expressions for the perimeter of the playground.

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= 2(L+B)= 2(2n+3+2n+3)

2(4n+6)= 8n+12A

Perimeter of the square playground= L+L+L+L=4L  42n+3+2n+3+2n+3+2n+3=4(2n+3)= 8n+12B

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
