How to calculate the area of ​​a rectangle mathematically

Haha, the reality doesn’t seem to be logical.....

Sometimes I feel like eating a donut, and at that time I put a sweet donut in my mouth without going against my desires.

What is the structure of the human body?

Experts who focus on the morphology of individual organisms and simplify their morphology to classify them assert that humans are donut-shaped.
In other words, they want to say that the human body is a donut-like structure with an entrance and an exit connected.
Sure, we can think of our human body as a donut-like structure, but that makes us feel uncomfortable.

How big is the tennis court?

One reason I feel uncomfortable

is that I know that donut-like structures are still not geometrically clean objects.
For example, we know how to calculate the area of ​​a rectangle mathematically. Long side x short side, right? Did you remember?
However, this simple formula is only valid in ideal situations. Both long and short sides should be straight lines. And these two straight lines must intersect at right angles.
But have you ever seen something like that in nature? Not only tennis courts, but also the model rectangular objects to which the above formula can be applied are only artificially created, and such a model shape does not exist in nature.

Let’s get back to the story

Everyone has seen and eaten donuts, but the donut-shaped image in our heads can still be thought of as a monster that is not well explained in the field of mathematics.
But we can make donuts, which are donut-shaped baked goods, and even if we can’t calculate their surface area, we can stick sugar to them. Haha, the reality doesn’t seem to be logical.
