After decomposing the trapezoid we found the area of each shape and

• subtracted the areas

• added the areas

• multiplied the areas

• divided the areas

to breakdown a shape into smaller (multiple) shapes is called

• congruent

• isosceles

• compose

• decompose

Find the area of the trapezoid.

Hint: Think about decomposing and rearranging.

• 28 sq units
