Answer/Step-by-step explanation:
Length of rectangular garden = 12.63 m
Width of rectangular garden = 3.28
Part A: Perimeter of garden if the length and height is rounded to nearest whole number.
12.63 rounded to nearest whole number = 13
3.28 rounded to nearest whole number = 3
Equation that shows her estimate would be: C. 13 + 3 + 13 + 3 = 32 meters
Part B: Perimeter of garden if the length and height is rounded to nearest tenth.
12.63 rounded to nearest tenth = 12.6
3.28 rounded to nearest tenth = 3.3
Equation that shows this estimate would be: B. 12.6 + 3.3 + 12.6 + 3.3 = 31.8 meters
Part C: Exact Perimeter of her garden.
Exact perimeter would be 12.63 + 3.28 + 12.63 + 3.28 = 31.82 meters
Part D:
Difference between 31.82 and the exact perimeter is 0.02, while difference between 32 and the exact perimeter is 0.18.
Therefore:
The numbers rounded to the nearest TENTH are closer because 31.8 meters is closer to the exact perimeter than 32 meters.
