Hey,,
Using Pythagoras theorem ,
15^2 =12^2+square of the distance between the parallel side
distance between the parallel sides=9cm
Now,
Area of trapezium=1/2*sum of parallel sides*distance between the parallel sides
=1/2*(12+36)*9
=1/2*48*9
=216.
Hope this helps you!!!!

what is the meaning of star
multiplication sign
height k jagah aap 9 di Hai pr height to 15 hai
height is not 15 ,15 is the value of the non parallel side
try n understand.. first make the figure in which the value of parallel sides are given and value of non parallel side is 15 so draw a perpendicular from one parallel side to the other and divide the other parallel side (on which perpendicular is drawn) into 12,12,and 12 and solve it accordingly!
height will be 9cm
