Question

two parallel sides of an isosceles trapezium are 6 cm and 14 cm respectively. if the length of each non - parallel side is 5 cm, find the area of the trapezium .
​

Answer 1

Answer:

Step-by-step explanation:

we know the area of the trapezium=1/2*sum of parallel sides*height

given

        it is isoceles 

        14-6=8cm

         8/2=4cm

          we have one non parallel side that is 5cm

           so h sq=5sq - 4sq

                 h=3cm

so area=1/2*20*3

              =30cmsq
