Determine the number of square yards of carpet needed for the office building in Figure 16.15. The carpet is 12 feet wide.
What will be an ideal response?
Run the carpet left and right to minimize the number of seams.
Length of carpet = 28?4? + 11?6? + 11?10? + 11?10? + 15?10? = 79?4?
Square yards of carpet = 79?4? × 12? / 9 sf per sy = 105.8 yd
