Here is a top down view of the table.

The purple semicirles are the leaves. The blue square is the table.

As you can see, the table can be split up into two shapes: a square and a circle.

The area without the drop leaves = the area of the square.

The area with the drop leaves = the area of the square + the area of the circle.

So... let's start by finding the area of each shape.

the area of the square = length * width = 4 * 4 = 16 sq. ft.

the area of the circle = π * radius2 = π * (4/2)2 = π * 22 = 4π sq. ft.

So..

The area without the drop leaves = the area of the square = 16 sq. ft.

The area with the drop leaves = the area of the square + the area of the circle. = 16 + 4π ≈ 28.566 sq. ft.
