Find the long base $ a $ of a trapezoid if short base $b = 2$ and median $m = 2$.
Answer
$a = 2$
Explanation
To find long base $ a $ use formula:
$$ m = \frac{ a + b } { 2 } $$After substituting $ m = 2 $ and $ b = 2 $ we have:
$$ 2 = \frac{ a + 2 } { 2 } $$ $$ 2 \cdot 2 = a + 2 $$ $$ a + 2 = 4 $$ $$ a = 4 - 2 $$ $$ a = 2 $$This page was created using
