First of all, you need to know the formula for a rectangle's perimeter.
Perimeter= 2length + 2width
You are given:
length= 12 meters
perimeter= 38 meters
-->Substitue in your information:
38= 2(12) + 2(width)
-->Simplify: 14 = 2(width)
-->Divide 2 on both sides: 7 = width
Therefore, the width of the rectangle is 7 meters.
