Question 1

A bathroom measures 7 ft 6 in × 9 ft 3 in. What is the area in square feet?

Accepted Answer

69.375 sq ft

Answer

Convert to decimals: 7.5 ft × 9.25 ft = 69.375 sq ft.

Question 2

When planning a herringbone pattern layout, what additional layout step is required compared to a standard straight layout?

Accepted Answer

A second chalk line perpendicular to the first must be established at the center

Answer

Herringbone layouts require two perpendicular reference lines intersecting at the center to keep the 90-degree alternating pattern aligned across the room.

Question 3

What is 'dry-laying' or 'dry-fitting' flooring before installation?

Accepted Answer

Installing flooring without adhesive to test the pattern and fit before committing to a permanent install

Answer

Dry-laying means temporarily placing flooring pieces without adhesive to verify the pattern, cuts, and layout before permanent installation.

Question 4

How many square feet are in a room that measures 13 ft × 15 ft, and how much material should you order if you add 10% for waste?

Accepted Answer

195 sq ft; order 214.5 sq ft

Answer

13 × 15 = 195 sq ft; 195 × 1.10 = 214.5 sq ft is the amount to order.

Question 5

When using the 3-4-5 triangle method to check if a layout line is square, what does it confirm?

Accepted Answer

That two reference lines are perpendicular (90 degrees) to each other

Answer

The 3-4-5 method (measuring 3 ft on one line, 4 ft on the other, and checking that the diagonal is 5 ft) confirms the two lines are at a true 90-degree angle.
