The area of a circle:  
Area = 

The area of a kite: 

To find the area of a kite, multiply the lengths of the two diagonals and divide by 2 (same as multiplying by 1/2): 

To find the area of a parallelogram, just multiply the base length (b) times the height (h): Area = b x h 

Go here to see where this formula comes from! 
The area of a rectangle:  
To find the area of a rectangle, just multiply the length times the width: Area = L x w 

The area of a rhombus:  
To find the area of a rhombus, multiply the lengths of the two diagonals and divide by 2 (same as multiplying by 1/2): 

The area of a square:  
To find the area of a square, multiply the lengths of two sides together... Another way to say this is to say "square the length of a side!" Get it? Square! 

The area of a trapezoid:  
To find the area of a trapezoid... The longer base (the bottom) is big B and the smaller base (the top) is little b... Go here to see where this formula comes from! 

How to find the area of strangely shaped objects:  
Let's find the area of this thing... We, basically, need to find the area of each color and add them all up. And we'll just have to find those areas one by one! 

Here are all the missing pieces: Now, add them all up! 6 + 4 + 32 + 6.28 = 48.28
