Question

if abcd is a adjacent trapezium then AD//BC.AD=1/3BC.If AD =9cm and perimeter of trapezium is 52 cm.THEN AB​

Answer 1

Answer:

Step-by-step explanation:

AD = 9cm & BC = 27cm & AB = CD

Perimeter of Trapezium = AD + BC + AB + CD

                             52 cm = 9cm + 27cm  + 2AB

                  52cm - 36cm = 2AB

                                   AB = 14cm/2

                                   AB = 7cm              Ans.
