Question
Find the diagonal $ d $ of a square if side $a = 30\, \text{mm}$.
Answer
$30 \sqrt{ 2 }\, \text{mm}$
Explanation
To find diagonal $ d $ use formula:
$$ d = \sqrt{ 2 } \cdot a $$After substituting $a = 30\, \text{mm}$ we have:
$$ d = \sqrt{ 2 } \cdot 30\, \text{mm} $$ $$ d = 30 \sqrt{ 2 }\, \text{mm} $$This page was created using
