Qn. 1 Lower bound for Zoe's weight = 62 - (1/2) = 62 - 0.5 = 61.5 kg
Qn. 2 Upper bound for length AB = 8.3+ (0.1/2) = 8.3+0.05 = 8.35 cm
Qn. 3 Upper bound for Anu's wight = 83+(0.5/2) = 83+0.25 = 83.25 kg
Qn. 4 Lower bound for length CD = 27-(0.5/2) = 27-0.25 = 26.75 cm
Qn. 5 Upper bound for sides of the hexagon = 3.6+(0.1/2) = 3.6+0.05 = 3.65 cm Upper bound for the perimeter = upper bound for the sides*6 = 3.65*6 = 21.9 cm
Qn. 6 Perimeter = 4*length => side = Perimeter/4 = 24/4 = 6 Bound = 0.5/4 = 0.125 Lower bound of the length = 6-0.125 = 5.875 cm
Qn. 7 For the area, Upper bound = 80+(10/2) 80+5 = 85 cm^2 For the length Upper bound = 12+(1/2) = 12+0.5 = 12.5
Then, upper bound for the width = Upper bound for the area/upper bound for the length = 85/12.5 = 6.8 cm
Qn. 8 Lower bound for the area = 230-(1/2) = 230-0.5 = 229.5 cm^2 Lower bound for the sides of the square = Sqrt(Lower bound of the area) = Sqrt (229.5) = 15.15 Then, Lower bound of perimeter = 4(Length) = 4*15.15 = 60.6 cm
