Draw a trapezium say abcd and join the diagonals you will obtain two triangle draw two perpendiculars on diagonals from both parallel sides now area of quadrilateral(trapezium)=sum of area of both the triangles let a and b be two parallel sides and h be the perpendiculars area of 1st triangle=1/2 x a x h ....1 area of 2nd triangle=1/2 x b x h .........2 sum of 1 and 2 = area of quadrilateral(trapezium) 1/2 x a x h +1/2 x b x h= area of trapezium 1/2 x (a+b) x h= area of trapezium (taking out 1/2 as common)
