What is an "oddly shaped rectangle"? Rectangles have four sides, with two pairs of sides that are equal in length and parallel to each other, and four right angles. Anything that fits this definition is a rectangle, period. There's nothing "odd" about any of them. But the area of any rectangle can be found by multiplying the lengths of any two adjacent sides.
Split the area up into shapes for which you can work out the area: rectangles and triangles. Then the area of the original room is the sum of all the areas.
It is not at all skewed. As to oddly shaped, it depends on your expectations.
A gerrymander.
Divide your oddly shaped room into smaller standard shapes. Calculate each smaller shape's area then add all of your answers together.
Geometric configurations that do not conform to standardized shapes (squares, triangles, circles, etc.) can still have their areas determined. They can be calculated by dividing the given parcel into known shapes (and thus formulae) and then calculating the areas of each, and combining their values.

Contours lines are oddly shaped because it goes according to how it is shaped.

Because the arsonist had oddly shaped feet.
Contour lines are oddly shaped because they represent points on the map that have the same elevation. They can curve, bend, or even form irregular shapes to show changes in the elevation of the land. These contours help us visualize the three-dimensional shape of the terrain on a two-dimensional map.
There are many "odd" shaped galaxies. Do a google search for irregular galaxies and take your pick. See related question.
