Question

Is it all right if we do the first question by the following method:
We will make a diagonal DB.
Then,
area of parallelogram = 1/2 area of triangle.
From there by putting area we can find the answer.
But my answer is coming wrong.
Can someone tell me what is wrong in this?​

Answer 1

Step-by-step explanation:

if a triangle and parallelogram have same base and between same parallel lines then you can take area of triangle = 1/2 of area of parallelogram

in the above problem you should not take like that
