Q18 of 99 Page 269

Any adjacent parallel sides of a trapezium makes an angle 45° and length of its slant side in 62 cm., what is the distance between two parallel sides.

Let us consider a trapezium ABCD, such that AB || CD and BC be the slant height such that BC = 62 cm, and ∠ABC = 45°


To find: Distance between two parallel lines i.e. CP.



In ΔACP


We know,






⇒ CP = 31√2 cm
