area of trapezium = 39 cm sq
height of trpezium = 6 cm
one || side = 5 cm
let other be x
area of trapezium = 1/2 × ( sum of || sides) × h
39 = 1/2 × ( 5+x) × 6
39×2 = (5+x) × 6
78/6 = 5+x
13-5 = x
8 = x
x = 8cm
hope it helped

Area of trapezium is 1\2 ×(sum of two sides)
×h
1/2 ×( sum of parallel sides)× height
so what i have written ? i have also written the same
|| sign is parallel sign
39=1\2×(5+x)×6.......78\6=5+x.....x=13-5 .....Therefore x=8cm
if you know the answer so answer it why are you typing all tgis in comments
this*
Thnk u so much

Answer:
if they gave one of parallel side is 8 cm
Step-by-step explanation:
area = a+b/2×h
39=8+x/2×6
13=8+x×3
13/3=8+x
x=13-8
x=5 cm
