here is ur answer....

Answer 2

HEY!
_______

We know that,

$area \: of \: trapezium \: \\ = \frac{1}{2} \times (sum \: of \: parallel \: sides) \times height$
let the altitude be 'h'
so, according to the question,
$210 = \frac{1}{2} \times (12 + 8) \times h \\ 210 = \frac{1}{2} \times 20 \times h \\ 210 = 10 \times h \\ h = \frac{210}{10} \\ h = 10 \: m$
