Question
Find the diagonal $ d $ of a rectangle if side $a = 27\, \text{cm}$ and side $b = 92\, \text{cm}$.
Answer
$\sqrt{ 9193 }\, \text{cm}$
Explanation
To find diagonal $ d $ use Pythagorean Theorem:
$$ a^2 + b^2 = d^2 $$After substituting $a = 27\, \text{cm}$ and $b = 92\, \text{cm}$ we have:
$$ \left( 27\, \text{cm} \right)^{2} + \left( 92\, \text{cm} \right)^{2} = d^2 $$ $$ 729\, \text{cm}^2 + 8464\, \text{cm}^2 = d^2 $$ $$ d^2 = 9193\, \text{cm}^2 $$ $$ d = \sqrt{ 9193\, \text{cm}^2 } $$$$ d = \sqrt{ 9193 }\, \text{cm} $$This page was created using
