In the termite barrier calculation example, what were the outside and inside perimeters used?

• A. Outside 5 feet; Inside 19 feet
• B. Outside 10 feet; Inside 20 feet
• C. Outside 3 feet; Inside 12 feet
• D. Outside 7 feet; Inside 21 feet

Answer: (A)

The thing this item tests is how termite barrier work uses two boundary lengths: the outside perimeter (around the structure’s exterior) and the inside perimeter (along the interior boundary). In the example, the exterior boundary is the shorter length and the interior boundary is the longer length. This shows how the interior layout can yield more boundary length than the outer edge, which affects how much barrier material is needed and how it’s applied. The correct option reflects that smaller outside perimeter paired with a larger inside perimeter. The other options would mix up that relationship or use values that don’t match the example’s geometry.
