error= 0.1/2, 0.05
4.8 + 0.05 = 4.85
6.3 + 0.05 = 6.35
4.85 x 6.35 = 30.7975 cm (when rounded, gives 30.80 cm).
4.8 + 0.05 = 4.85
6.3 + 0.05 = 6.35
4.85 x 6.35 = 30.7975 cm (when rounded, gives 30.80 cm).
The upper bound for the area of the rectangle is 30.24 cm².
A rectangle is a shape with four sides. The sum of angles in a rectangle sums up to 360 degrees. The area of a rectangle = length x width
When correcting a figure to one decimal place, numbers in the hundredth position that is greater or equal to 5, would increase the tenth figure by 1. If the number in the hundredth position is less than 5, the tenth figure remains unchanged.
Possible dimensions of the rectangle before correcting to one decimal place:
6.25, 6.26, 6.27, 6.28, 6.29 6.30
4.75, 4.76, 4.77, 4.78, 4.79, 4.80
The upper bound for the area = 6.3 x 4.80 = 30.24 cm²
