it must be less than 5*2

The non-visible DrEck on the left is 2 high and (5-3) wide at the top

Area 2*2/2 = 2

.

Total A is 10 – 2 (with TR for safety )

In addition to the proposal of , you can also simply use the surface formula for a trapezium:

The shape is composed of a rectangle and a rectangular triangle. Simples to calculate.

Split into rectangle and triangle…The triangle has half the surface of the respective square!

either divide the area into triangle and square,

or consider the mean from the upper and lower sides as a rectangle side,

or use the surface formula for the trapezium.

If it’s so easy, why do you write a wrong result?

And unfortunately wrong. But do nix, not everyone dominates the correct multiplication or the correct application of the surface formulas.

No, that’s not the formula. If you don’t know, you should either not answer or at least research correctly.

16 is therefore grade 8^2 the formula is at the top + multiplied by height
