@irina there's a lot I've forgotten from school over the past 20 years, but I'll always remember:

Half the sum of the parallel sides
Times the distance between them
That's the way the trapezium goes
Pop goes the answer 😁

@irina @noctuaminervae

This is like…

Twinkle Twinkle little star
Power equals I² R

or is it

Little star way up high
Power equals R² I

🤔
