In a trapezium, one diagonal divides the other in the ratio 2 : 9. If the length of the larger of the two parallel sides is 45 cm, then what is the length (in cm) of the other parallel side?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1. (i.e. 10)

Here, ΔAOB ~ ΔCOD

So, 

AO/CO = AB/CD

⇒ 2/9 = AB/45

⇒ AB = 10 cm
