Perimeter of Trapezium

Perimeter of A Trapezium:

The perimeter of a trapezoid is the sum of the lengths of its four sides.

Illustration:  If the perimeter of a trapezium be 52 cm, its non- parallel sides are equal to 10 cm each and its altitude is 8 cm, find the area of trapezium.

Solution : We have,  Perimeter of the trapezium = 52 cm, Altitude of the trapezium = 8 cm

Sum of the parallel sides + Sum  of the non-parallel sides =52 cm : Sum of the parallel sides = (52 - 20 ) cm =32 cm.

large therefore   Area ;of ;the; trapezium =frac{1}{2}times(Sum ;of ;the; parallel; sides) times Altitude

                                                      =frac{1}{2} times 32 ;times 8;cm^{2} = 128; cm^{2}
