Question

the area of a Trapezium is 195 CM 2 and its height is 9 CM. if one of the parallel sides is longer than the other by your centimetre. find the two parallel side ​

Answer 1

Take the first parallel side be x

then other side=x+4

we know

area of trapezium as 1/2(sum of it's parallel side)×h

=1/2(2x+4)×9

=>(x+2)×9=195

=>x+2=21.6

=>x=19.6

other side

=>19.6+4=23.6
