Formulas for frames

Inside length
\(\displaystyle a`= a-2·c\)

Inside height
\(\displaystyle b`= b-2·c\)

Frame diagonal
\(\displaystyle d= c·\sqrt{2}\)

Inside diagonal
\(\displaystyle d`= \sqrt{a`^2+b`^2}\)

Perimeter
\(\displaystyle P= 2·(a+b+a`+b`)\)

Frame area
\(\displaystyle A= a·b-a`·\;b`\;\;\;=a·b-A`\)

Inside area
\(\displaystyle A`= a`·\;b`\)
