I'm not a fan of math, however, the content presented was rather interesting. The presenter also sounds very enthusiastic. Great work, sir 👍.

Isn't the 2r in the perimeter supposed to be 2r(2), which equals 4r ? because the length is 2r and we have two lengths, so we have two 2rs. If not, please assist Mr Kevin.

[nhlanhlamngomezulu]

Wouldn’t it be 60 = 4r + 2b + pie for perimeter instead of 2r ? Because b became 2b so 2r should become 4r🤷‍♂️
