What will I be doing today ?

• Decompose composite geometric figures into rectangles, parallelograms, and/or triangles to determine their areas.

• Solve real-world problems by composing and decomposing shapes into triangles and rectangles

Multiple Choice

What is an an example of a composite figure ?

You'll need more than one formula since you have more than one shape !!!

Area of a Triangle= 1/2BXH

Area of a rectangle= L X W

Area of a Circle = 3.14 X R^2
