Hi Titanium

Correct, a diagonal cut will produce 2 right angled triangles.

 

After that your air waves got a bit scrambled.   LOL.  :)

To find the area of a sliced rectangle when cut diagonally, first we must know the facts of rectangles, or quadrilaterals as we say when it comes to measurement

Rectangle:

its angles equal 360 degrees-

basically its 2 triangles-

Triangle:

half a rectangle-

angles equal 180 degrees

so pretty much, half of a rectangle is a triangle

to find the area of one of the pieces, you must do the triangle formula, which is:

$${\frac{{\mathtt{h}}{\mathtt{\,\times\,}}{\mathtt{b}}}{{\mathtt{2}}}}$$

To combine the area of both mini rectangles and make it the original rectangle, just multiply by 2 or simply dont divide by 2 and just multiply h*b, which is l*w basically

the triangle is half of a rectangle becuz its angles equal 180 degrees, times it by 2 (both halfs), it equals 360 degrees, the amount of degrees in a quadrilateral, not only rectangles, but also squares

hope this helps!
