Find the median $ m $ of a trapezoid if long base $a = 56\, \text{cm}$ and short base $b = 35\, \text{cm}$.
Answer
$\frac{ 91 }{ 2 }\, \text{cm}$
Explanation
To find median $ m $ use formula:
$$ m = \frac{ a + b } { 2 } $$
After substituting $ a = 56 $ and $ b = 35 $ we have:
$$ m = \frac{ 56 + 35 } { 2 } $$ $$ m = \frac{ 91 } { 2 } $$ $$ m = \frac{ 91 }{ 2 } $$
