If it is a regular hexagon, then it can be divided up into 6 equilateral triangles each of side 19 yards. Using Pythagoras, the height of those triangles is 19 x (√3)/2
→ area hexagon = 6 x 1/2 x 19 x (19 x (√3)/2) = 1083/2 √3 ≈ 937.9 sq yds (to 1 dp)
The apothem of the hexagon is 19 x (√3)/2 ≈ 16.454 = 16.5 rounded to 1 dp.
Area regular hexagon = 3 x side x apothem = 3 x 19 yd x 16.5 yd = 940.5 sq yd
This shows the importance of only rounding answers at the end, and if rounding must take place before the end, working with more digits than required for the answer so that it can be rounded with less loss of accuracy:
Working with the apothem to 2 dp:
area = 3 x 19 x 16.45 = 937.65 → 937.7 to 1 dp. (closer to the real area).
Working with the apothem to 3 dp gives:
area = 3 x 19 x 16.454 = 937.87 → 937.9 to 1 dp. (same to 1 dp)

Given the perimeter of a regular hexagon, it is better to use the side length: 6 inches, rather than the apothem of 5.2 inches because the latter is he rounded value of 3*sqrt(3) which is 5.196152... rather than 5.2. Based on the length of the sides, the area is approx 93.53 sq inches. [The apothem would have given 93.67 sq inches.]
The hexagon will consist of 6 equilateral triangles of 3 equal sides of 10 cm and the apothem will divide the triangle into 2 right angle triangles with a base of 5 and an hypotenuse of 10 and so by using Pythagoras' theorem the height of the triangle which is the apothem works out as 5 times square root of 3 or about 8.66 cm rounded to 2 decimal places.
The area is 162.4 square inches.If apothem = x, then area = 8*x^2*tan(180/8)If side = s, then area = 8*s^2/(4*tan(180/8))
If you mean an apothem of 4.82 inches rounded to two decimal places then its area is 0.5*4.82*7*5 = 84.35 square inches.
The hexagon will consist of 6 equilateral triangles having sides of 20 cm and so:- Area of the regular hexagon: 0.5*20*20*sin(60 degrees)*6 = 1039 square cm rounded
Rounded to the nearest whole number 5.5 is 6

When rounded to the nearest hundredths, 100.147 is rounded to 100.15. When rounded to the nearest tenths, it is rounded to 100.1. When rounded to the nearest hundreds, it is rounded to 100.
6.6273 rounded to the nearest thousandths is 6.627 Rounded to the nearest hundredths, it is 6.63. Rounded to the nearest tenths, it it 6.6. Rounded to the nearest ones, it is 7.
853 rounded to the nearest 100: 900. 10853 rounded to the nearest 100: 10900.
133.06 rounded: Rounded to the nearest tenth: 133.1 Rounded to the nearest whole: 134 Rounded to the nearest ten: 130 Rounded to the nearest hundred: 100
the 3746 rounded to nearest 100 would be 3700 and rounded to nearest 10 would be 3750 so definitely 3746 rounded to nearest 10 is greater than nearest 100.
