Question

$the \: area \: of \: a \: trapezium \: is \\ {1080cm}^{2} .if \: the \: lengths \: of \: its \\ parallel \: sides \: be \: 55cm \: and \: \\ 35cm.find \: the \: distance \: \\ between \: them.$

Answer 1

$\boxed{your \: answer.......}$
$\bf{length \: of \: parallel \: sides \: are \: 55cm \: and \: 35cm \: \: \: \: \: \: \: \: \: sum \: of \: parallel \: sides = (55 + 35)cm = 90cm \: \: \: \: \: let \: distance \: between \: the \: two \: sides = x \: cm \: \: \: \: \: area \: of \: trapezium \: = 1080cm^{2} \: \: \: \: \: \: \: \: \: \frac{1}{2} \times (sum \: of \: parallel \: sides) \times (distance \: between \: them) = 1080 \: \: \: \: \frac{1}{2} \times 90 \times \: x \: = \: 1080 \: \: \: \: \:90x = 1080 \: \: \: \: x \: = 24cm}$
