Steps:
1. Draw a line connecting the point to the center of the rectangle
2. Then construct a perpendicular bisector to the line drawn in step 1
3. Place the compass on the midpoint of the line, adjust its length to reach the end point, and draw an arc across the circle
4. Where the arc crosses the circle will be the tangent points. So connect the endpoint to the tangent point

Check the picture below.
so, if we slap the bottom surplus to the empty area on the top, we can pretty much close off those squares above, that gives a solid area of at least a 4x5 square, the red part and the yellow part there, and that'd give us a perimeter of 4+4+5+5 = 20 at least.
we might also be able to augment the left-right sides together to close off those squares as well, but even if we did, our area will just be about a 4x6 or 24 square units.
A) is the area larger than 14 square units? ✔
B) is the area less than 35 square units? ✔
C) is the perimeter more than 16? ✔
