Question

What is the length of the non-parallel sides in an isosceles trapezium if the perimeter is

256 cm and the lengths of the two parallel sides are 60 cm and 86 cm respectively?​

Answer 1

Answer:

$perimeter = sum \: of \: all \: side$

$let \: the \: non \: parallel \: side \: be \: \: \: \: x$

$256 = 60 + 86 + 2x$

$256 = 146 - 2x$

$110 = 2x$

$x = \frac{110}{2}$

$x = 55$ so the non parallel sides are 55cm
