Question

Area and altitude of trapezium are 3000 sq. cm and 40 cm respectively. One of the parallel sides is double the other. Find the length of the longer side. *​

Answer 1

Answer:100 cm

Step-by-step explanation:

=> let the parallel side be x and 2x respectively.

=> Given,

               Area= 3000 cm^2

               Altitude= 40 cm.

=> Now, area of trapezium = (sum of parallel side/2)*height

=>                        3000 = (2x+x/2)*40

                          3000 = (3x/2)*40

                          3000= 120x/2

                          60x= 3000

                             x= 50 cm.

 Hence, Longest side= 2x= 2*50= 100 cm.
