Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

$P Q R S$ and $P Q U I$ are two $∥$ gm on the same base $P Q$ and between some $∥$ als. Therefore, to measure the area of both the $∥$ gms the $⊥$ ar drawn TV is equal for both the $∥$ gms & this is the height of $∥$ gms. The area calculated will be same for both the $∥$ gms because, area of two $∥$ gms on same base and between same $∥$ als will be equal.

Hence Option (A) is correct.
