PLEASE HELP ME!!! (brainiest to the one who gets it right for me.) Whitney is showing how to model the
area formula of a trapezoid.
1) Original trapezoid
b,
b)
b.
b
2) Create a congruent trapezoid
Flip it then join it to the original
trapezoid. This forms a
parallelogram
Due:
b,
b.
b + b 2
3) Decompose the parallelogram
into a right triangle and a trapezoid.
b + b
4) Rearrange the triangle and
trapezoid to form a rectangle
5.4
The area of the original trapezoid will be -
A the area of the triangle in step 4
B half the area of the rectangle in step 4
C the area of the trapezoid in step 4
D the area of the rectangle in step 4
