Answer 1

Consider first the size of the original rectangle: it is 20x15=300 square meters.

Now consider the piece removed.

The four quadrants make a circle with area pi*(3.5*3.5).

That is about 38.5. Subtract this from the are of the rectangle, 300, and you get 261.5 square meters.

Answer:- Area of remaining part is 261.5 square metre.
