Find the lateral area $ LA $ of a triangular prism if side $a = 12$ and length $l = 20$.
Answer
$AL = 720$
Explanation
To find lateral $ AL $ use formula:
$$ AL = 3 \cdot a \cdot l $$After substituting $ a = 12 $ and $ l = 20 $ we have:
$$ AL = 36 \cdot 20 $$$$ AL = 720 $$This page was created using
