There are 3 097 600 square yards in a square mile.
9 is the best estimate whole number
The square root of 72 is approximately 8.49. Since we are looking for the best integer estimate, we can round this value to the nearest whole number, which is 8. Therefore, the best integer estimate for the square root of 72 is 8.

Since sqrt(52) is an irrational number, the best estimate is √52. Any decimal estimate can be improved by adding another digit so none can be BEST.
It is best to do the conversion in lengths first. There are 1.0936133 yards in a metre. So a squate metre is 1.09361332 square yards. This is 1.19599004993689, so we need to multiply the number of square metres by this. 50 x 1.19599004993689 = 59.7995024968445 Therefore, 50m2 is equal to 59.8yds2
The best answer I came up with is this. We know that the Atlantic Ocean is 33,420,000 square miles. And there are 1,760 yards in a mile and that gives us 58,819,200,000 square yards.

2.25 is a 'best guess'. 2.25 x 2.25 = 5.0625
You need not estimate since all 4 sides of a square are congruent. The perimeter is 116 (or 29 * 4)
