There are 3 097 600 square yards in a square mile.
9 is the best estimate whole number
foot
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.
English units--square feet or square yards. Metric--square meters

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)
The squareroot of 539 is 23.21637353 If you estimate it, the best approximated answer will be 23.22
