I think the correct option is not there in the 4 options you provided.

Ideally if you can create two squares with a partition of 7m, one of the sides of the squares has to be 7m.
In that case, the area of each square will be 49sqm and the area of the rectangle should be 49*2 = 98sqm.

What is the OA?
