Question

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?

Answer 1

Answer: Side length(s): 20.4. Variable (s) = 15

Step-by-step explanation:

Side Length: 102/5 = 20.4

Variable (s) = 6s + 12 = 102

102 - 12 = 90

90/6 = 15

s = 15

Answer 2

* 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
