Rectangle
A = b . h
Triangle
A=1/2bh OR A=b . h /2
Parallelogram
A = b . h
Trapezoid
A=b1+b2 /2 . h

total area of all outer faces on a 3D object (measure in square units)
Prism
3D figure that has two base shapes (polygons) that are congruent and parallel to each other
Pyramid
3D figure with a polygon as a base and triangular faces that taper up to a point (vertex/apex)
