Difference of two parallel sides of atrapezium is 4cm. perpendicular distance between them is10cm. If the area of the trapezium is 250cm^2. Find the lengths of the parallel side?	Choose the correct choice from the following choices:  A) 20 cm and 21 cm  B) 25 cm and 23 cm  C) 27 cm and 23 cm  D) 30 cm and 34 cm  E) 28 cm and 36 cm
Let the two parallel sides of the trapezium be a cm and b cm.   Then, a-b = 4 ------ (1)   And, (1/2) x (a+b) x 10 = 475 =&gt;(a+b) =((250 x 2)/10) =&gt; a + b = 50------- (2)   Solving 1 and 2, we get: a=27,b=23   So, the two parallel sides are 27 cm and 23 cm.   27 cm and 23 cm
