heptagon, and octagon are shown in figure 1-4.
A trapezoid, trapezium, rhombus, and rhomboid
are shown in figure 1-5.
DETERMINING AREAS
The area of any surface is the number of units
of area measure the surface contains. A unit of
area measure is a square unit. The main thing to
remember when computing for areas is that the
dimensions used must be of the same unit of
measure—if in inches, all units must be in inches
and if in feet, all must be in feet.
