Which shapes did you choose?

Which formulas will you use?

Let's start with the rectangle.

EASY PEASY :)

Which two numbers would you use? A = b * h

A = b * h

What is the area of the rectangle?

A = $$\frac{1}{2}$$  b * h

Time for the TRIANGLE!

What is the b (base) of the triangle?

A = $$\frac{1}{2}$$  b * h

What is the h (height) of the triangle?

A = $$\frac{1}{2}$$  b * h

What is the area?

A = $$\frac{1}{2}$$  * 4 * 4

Once you find the area of the rectangle and the area of the triangle, ADD them together to get the total area of the composite figure.

Which is the BEST?

What numbers will you use for the triangle?

A = $$\frac{1}{2}$$   b * h

What is the area of the triangle?

What numbers will you use for the rectangle?

A = b * h

What is the area of the rectangle?

A = $$\pi\cdot r^2$$  

Which number represents r?

A = $$\pi\cdot r^2$$  

What is the area a FULL circle?

A = $$\pi\cdot r^2$$  

What is the area a $$\frac{full\ circle}{2}$$  ?

Area of the triangle = 

Area of the rectangle =

Area of the semi circle (half the circle) =

What is the total area of the composite figure? (add all of the areas...go back if you need to)
