Question

find area of trapezium whose parallel sides 25 cm, 13 cm, and other sides are 15cm and 15 cm?

Answer 1

area of trapezium  = 1/2 x ( sum of parallel sides ) x other side
                              = 1/2 x (25+13) x 15
                              = 1/2 x 38 x 15
                              = 19 x 15
                              = 285 cm 

Answer 2

area of a trap is =1/2*(b1+b2)×h

area = 1/2×38*15

area =19×15

area =285cm^2
