Mmm i misunderstood...was thinking the difference as in 40 - 12 = 28 for non-shaded perimeter, 12 for shaded. So then 2*10 = 20 / 2 = 10 cm2.
That is some hard math for a 12 year old! Although it's been a long, long time for me. I always enjoyed math, wish i had stuck with it more...
Same here.
Now I have to relearn my Maths so that I can marshal my children through the education system.
This question is actually easy peasy because I can solve it. Thank you for the interest. Gives me the motivation to find those questions that have left me stumped. (I don’t even understand how to solve them after reading the worked solutions 🥲)
