Question:
finding the circumference of a circle? formula
finding the area of a parallelogram? formula
 

The circumference of a circle is a formula you need to know. The circumference of a circle is given by 2 pi times the radius. You however don't need a formula to find the area of a parallelogram. Just imagine that you take your scissors, cut off the triangle at one end by making a cut perpendicular to the base, and move it to the other end. Now you have a rectangle with the same area as the parallelogram and you can easily find the area of the rectangle as its base times its height.
