Multiply the length by the wide. eg a 3cm x 6cm rectangle - 3x6=18sqcm
The answer is in square units, - square feet, metres, mm etc
You could consider the cross as two intersecting rectangles. Calculate the area of both rectangles and the area of the intersection (overlap). Then area of cross = sum of the areas of the rectangles minus the area of the overlap.
To find the area of combined rectangles, first calculate the area of each individual rectangle by multiplying its length by its width. Then, add the areas of all rectangles together. If the rectangles overlap, subtract the area of the overlapping section to avoid double-counting. Ensure all measurements are in the same unit for accurate calculations.
Perimeter: add all sides area: multiply length times width for rectangles
There is no such thing as an "irregular rectangle". To calculate the area of a rectangle - if that's what you mean - you multiply length x width.
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".

Treat it as two rectangles - calculate the area of each rectangle - then simply add the two figures together.

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.

An L is two rectangles. Just make sure you only count the place where they intersect once.
To calculate the area of an L-shaped figure, divide the shape into two rectangles, calculate the area of each rectangle by multiplying their length and width, and then sum the areas. For the perimeter, measure the lengths of all the outer edges, adding them together while ensuring not to double-count any shared sides between the rectangles. Alternatively, you can also use a grid method to count the unit squares for area and measure the outer boundary for perimeter.
Divide the room into two rectangles. Then calculate the area of each rectangle as length x width.
divide the beam into three rectangles, calculate the area of each rectangle and multiply it by length. then you get the volume of beam & finally multiply it by density
An L-shaped area can be divided into two rectangles. The total area is the sum of the areas of the two rectangles.
