Question

The perimetre of a trapezium is 104 cm and the non parallel sides are 18cm 22 cm then its altitude is 16cm then area of trapezium is

Answer 1

Answer:

we know rhat perimeter is sum of all sides

and it is given 104 cm

and non parellel sides is given.

so sum of the two parellel sides is =perimeter - sum of non parelle sides

=104-(18+22)

=64

now altitude is also given

which is 16cm

and we now that area =1/2×sum of parelle side ×altitude

=1/2×64×16cm^2

=512cm^2
