Area of square |
A^2,where A is the length of one side |
|
|
Area of rectangle |
Length * height |
|
|
Area of parallelogram |
Base * height (to calculate height, extend the base so as to create an imaginary right triangle. Then use Pythagorean theorem to calculate base and height.) |
|
|
Area of trapezoid |
H/2(b1 + b2) Create a right triangle by extending a line from the end of the lines base to the intersection of an imaginary like from the shorter base (this will create a right triangle, from which height and hypotenuse can be calculated)? |

|
Area of circle |
¶r^2 |
|
|
Area of ellipse |
¶) (r1 + r2) (because an ellipse had two radii one from top to bottom and another from side to side) |
