length of first parallel side is2x
length of second parallel side is 3x
ACCORDING TO QUESTION
area of trapezium = 1/2×h×(a+b)
125cmsq. =1/2×10×(2x+3x)
125cm sq. =5×(2x+3x)
125cm sq. = 10x+15x
125cm sq. = 25x
125/25. =x
5cm. =x
the length of first parallel side will be 2x = 5×2=10cm
the length of second parallel side will be 3x=3×5=15cm
length of second parallel side is 3x

Answer:
10 cm and 15 cm
Step-by-step explanation:
Let the parallel sides of a trapezium be 2x and 3x respectively.
Area of trapezium = 125 cm²
According to the question ;
Area of trapezium = * (sum of || sides ) * h
⇒ Area of trapezium = * (2x + 3x) * 10
⇒ 125 = 5 ( 2x + 3x )
⇒ 5x = 125 / 5
⇒ 5x = 25
⇒ x = 25 / 5
⇒ x = 5
Therefore, parallel sides are ;
2x = 2 * 5 = 10 cm
3x = 3 * 5 = 15 cm
