Area of Shapes and Decompose

This is a distance (line) that is  perpendicular to the base of a parallelogram or triangle and is needed to find the area of those shapes.

• Height

• Parallelogram

• Area

This is the formula to find the area of which shape?

• parallelogram

• triangle

the number of square units that covers a two-dimensional region, without gaps or overlaps

• Area

• Perpendicular

• Decompose

means “take apart.” We use this word  to describe taking a figure apart to make more than one new shape

• Compose

• Area

• Decompose

What is the area of this shape?

• 63 cm2

• 37 cm2

• 73 cm2

• 36 cm2

Select all the true statements about this shape (Hint: Select all means more than one)

• The area can be found by decomposing into rectangles

• The area cannot be found because there are too many measurements

• The area can be found by multiplying 60x30 and subtracting missing pieces

• The area can be found by adding all the side lengths together

Decompose the irregular shape and find its total area.

• 96 units2

• 152 units2

• 192 units2

• 240 units2
