Find the side $ b $ of a rectangle if side $a = 24$ and diagonal $d = 25$.
Answer
$b = 7$
Explanation
To find side $ b $ use Pythagorean Theorem:
$$ a^2 + b^2 = d^2 $$After substituting $ a = 24 $ and $ d = 25 $ we have:
$$ 24^2 + b^2 = 25^2 $$ $$ b^2 = 25^2 - 24^2 $$ $$ b^2 = 625 - 576 $$ $$ b^2 = 49 $$ $$ b = \sqrt{ 49 } $$$$ b = 7 $$This page was created using
