We learned 3 different ways to find the area of a ​ (a)   . When we ​find the area by (b)   ​ we break the trapezoid into 1 ​rectangle and ​ (c)   ​ triangles . When we compose in order to find the area, we copy, flip, and put it side by side to make a ​ (d)   . The last way we learned to find its area was using the formula: ​ ​ ​ ​ ​ (e)  

• trapezoid

• parallelogram

• circle

• decomposing

• 1 or 2

• hexagon

• multiply

• A=BH

• 2
