Question

The perimeter of the school crossing sign is 102 inches. What is the length of each side?

Equation: _ =102
s=_


Question 2
Label the length of each side in inches

Answer 1

1) s=15

2) 15, 21, 21, 15, 30 from left to right

Explanation:

First you turn this into an equation: s+6+s+6+s+s+2s

Collect like terms: 4s+ 12 + 2s

Simplify: 6s+12

Bring back into a full equation: 6s+12=102

Simplify= 102-12=6s

90= 6s

90/6=s

s=15

Then bring back into sides: Left side and right sides are 15 as s= 15

15+6= 21 so both top sides are 21

2×15=30

So it goes in the order from left to bottom clockwise:

15, 21, 21, 15, 30
