2 Dimensional Area.
Area is the part of
any shape that
"covers" the surface
from edge to edge
- Triangle
Requires the
Base (b) and
Height (h) always
needs a Right
angle or
perpendicular
- A = 1/2
(b)(h)
- P = S+S+S
- A = 1/2
(b)(h)
- Parallelogram/Rectangle/Square Require
two pairs of paralle sides and opposite
sides are congruent
- A = (b)(h)
- P = S+S+S+S
- A = (b)(h)
- Trapezoid
Requires two
Bases(b), that are
parallel to each
other and
perpendicular to
the Height (h)
- A = 1/2(b + b)(h)
- P = S+S+S+S
- A = 1/2(b + b)(h)
- Circle Requires either
the Diameter/d
(Chord from edge
through center to
opposite edge, cut
circle into two equal
halves), or the
Radius/r (segment
from center to the
edge).
- A =
- C =
- A =
- Perimeter (P)
represents the
connected exterior
edges/sides (S) of a
shape, calculated by
adding the
measures of each
edge/side (S)
