Question

the area of a Trapezium in 120 metre square and its height is 12 m if one of the parallel side is longer than the other by 10 metre find the length of the parallel sides​

Answer 1

Answer:

Let  1st parallel side be x

2nd side =x+10

Ar of trap=120 m²

ar =1/2 *(sum of parallel sides)*hieght

120*2=(x+x+10)*12

240/12=2x+10

20=2x+10

2x=20-10

2x=10

x=10/2

x=5

1st parallel side=5 cm

2nd parallel side=5+10=15 cm
