just cut the rectangles into equal ones.
You divide the shape into smaller shapes you can calculate, like rectangles and triangles. If the shape is irregular, you have to approximate, for example by dividing it into many narrow rectangles. This technique is called "integration".
By integration - you divide the figure into many thin slices, and calculate the volume of each slice individually. The volume of each slice, again, can be calculated by integration: divide it into thin rectangles, and calculate the area of each rectangle. If you have a irregular solid figure just immerse it in water and measure the displacement. a la Archimedes
You approximate the irregular shape with many small regular figure, for example, long and thin rectangles.
Partition (or divide) the irregular object into summation of regular objects and then calculate the volume.

By integration. In general, if you have an irregular area, divide it into many small shapes, for example rectangles, which you know how to calculate.
You divide the shape into smaller shapes you can calculate, like rectangles and triangles. If the shape is irregular, you have to approximate, for example by dividing it into many narrow rectangles. This technique is called "integration".
If the figure is irregular, you can't calculate its area (for example) with some simple formula. You need to use integration - which basically means to divide the figure into many narrow strips, which you assume to be rectangles.
Rhombuses, rectangles, kites, parallelograms, and trapezoids are all irregular quadrilaterals.
The irregular plural form of "strategy" is "strategies."
Two triangles can but its an irregular shape
Regular shapes have equal sides and angles, like squares and equilateral triangles. Irregular shapes have sides and angles of varying lengths and measurements, like rectangles and scalene triangles. Regular shapes are typically easier to calculate and work with compared to irregular shapes.

The plural form for the noun strategy is strategies.

You approximate it with many small rectangles. This is known as integration.
