Break the shapes into smaller shapes, find the area (BxH) of the smaller shapes and add the areas of the smaller shapes together to get the total.
If you search for the topic online, it's typically said "area of complex figures."

Yes, you break down the figure into smaller recognizable shapes and then add those areas together. Do not assume all the new figures will be the same. You may get a trapezoid or a triangle. In which case you have to use the area formulas for those figures.

Divide the irregular shape into several regular shapes, calculate the area of each regular shape, respectively, and then add them up.

turn the irregular shapes into similar shapes and find the area for those, then add them together.
for example: if you had a rectangle, you can turn it into 2 triangles, and add the area of those together.

when the shape's irregular i usually subtract and add sides until its regular shape then you do the area thing.
