Question

the area of trapezium is 98 CM square and its height is 7 cm if one of the parallel side is 6 CM longer than other find the length of two parallel sides

Answer 1

the length of two sides is 11 cm and 15 cm

Answer 2

hi friend ......

here is your answer..


area of trapezium=98cm2

h=7cm

let the sides be = x and 6+x


$98 = 1 \div 2 \times h \times (6 + x + x)$
$98 = 1 \div 2 \times 7 \times6 + 2x$

$98 \times 7 \div 2 = 6 + 2x$

$2 x = 343 - 6$

$x = 337 \div 2$
