Question

The length between the parallel side of a Trapezium is 15 cm and parallel side measure 12 cm * 8 cm find the area of trapezium

Answer 1

$\bold{given : } \\ \\in \: a \: trapezium \\ \\ \bold{length \: between \: parallel \: sides : } \\ \\ 15 \: cm \: \\ \\ \bold{parallel \: sides : } \\ \\ 12 \: cm \: and \: 8 \: cm \: \\ \\ \\ \\ \bold{to \: find : } \\ \\ the \: area \: of \: trapezium \: \\ \\ \\ \\ \bold{area \: of \: a \: trapezium : }$
$\bold{ \frac{1}{2} \times sum \: of \: lengths \: of \: parallel \: } \\ \\ \bold{sides \: \times height} \\ \\ \frac{1}{2} \times (12 + 8 \: cm \: ) \times 15 \:cm \\ \\ \frac{1}{2} \times 20\:cm \times 15\:cm \\ \\ 10 \times 15 \\ \\ \bold{150 {cm}^{2} }$
