Write and solve an equation to answer the question. The perimeter of the school crossing sign is 102 inches. What is the length of each side?

* See the picture

Perimeter = The sum of the lengths of its sides

102 = 2s + s + s + ( s + 6 ) + ( s + 6 )

102 = 6 s + 12

6s = 102 – 12

6s = 90

s = 90 / 6

s = 15

So;

2S = 2 (15) = 30

S = 15

S = 15

S + 6 = 15 + 6 = 21

S + 6 = 21
