Question

the parallel sides of a trapezium are 25cm and 13 CM it's non parallel sides are equal each being 10cm. find the area of the trapezium.

Answer 1

to find area of trapezium = 1/2 * h * ( a + b )
  here h is height and a and b is parallel side
   so area of this figure is 1/2 * 10 * ( 25 + 13 )
                                    = 1/2 * 380
                                      =  190
so area of this trapezium is 190 cm2.
