Find the side $ a $ of a rhombus if diagonal $d_1 = 24$ and diagonal $d_2 = 18$.
Answer
$a = 15$
Explanation
To find side $ a $ use formula:
$$ d_1^2 + d_2^2 = 4 \cdot a^2 $$After substituting $ d_1 = 24 $ and $ d_2 = 18 $ we have:
$$ 24^2 + 18^2 = 4 \cdot a^2 $$ $$ 576 + 324 = 4 \cdot a^2 $$ $$ 4 \cdot a^2 = 900 $$ $$ a^2 = \frac{ 900 }{ 4 } $$ $$ a^2 = 225 $$ $$ a = \sqrt{ 225 } $$$$ a = 15 $$This page was created using
