Hi chetan2u
Can you please provide a solution to this one.
I get why D is the answer.
But can't B and C be the answer choice.

Thanks

While I agree that D is accurate and leaves us with a rectangle, I initially picked B thinking that this would be a square (combining 2 45 45 90 triangles forming a square). So, I would also like to know why B is wrong if someone can explain.

Thanks!

For Option B, the two diagrams are given below. According to me, since we can get two different type of quadrilateral, we cannot answer what would be the area with surety.

Even in the case of Option C, we can get two different types of quadrilateral and hence the area would differ and with the limited information given, I don't think we can even find the area, with just the angles and sum of lengths.
