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

• A=LW
• 4
• area
• height
• divide
• 3.25 cm2
• 6R5
• 6.5 cm2
