# Two opposite sides of a parallelogram have lengths of #25 #. If one corner of the parallelogram has an angle of #pi/4 # and the parallelogram's area is #45 #, how long are the other two sides?

The length of the second side is

In this task we have the area, one side and one angle of a paralellogram given.

One of methods of calculating the area is using the formula:

After transforming this formula we get:

After substituting the given values we get:

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- What are the rotational symmetry orders of the following: Parallelogram, Rectangle, Square, Rhombus, Kite and Trapezium? (Note: Trapezium, not Trapezoid)
- Two rhombuses have sides with lengths of #4 #. If one rhombus has a corner with an angle of #(7pi)/12 # and the other has a corner with an angle of #(3pi)/4 #, what is the difference between the areas of the rhombuses?
- Two rhombuses have sides with lengths of #8 #. If one rhombus has a corner with an angle of #pi/12 # and the other has a corner with an angle of #(5pi)/8 #, what is the difference between the areas of the rhombuses?
- What special type of quadrilateral has diagonals that are congruent and bisect but are not perpendicular?
