Answer: Area (upper bound) = 4527.7056 cm²
Perimeter (lower bound) = 278 cm
Step-by-step explanation:
The length and width of the rectangle have been ROUNDED to the nearest tenth. Let's calculate what their actual measurements could be:
LENGTH: rounded to 87.3, actual is between 87.25 and 87.34
87.25 is the lowest number it could be that would round it UP to 87.3
87.34 is the highest number it could be that would round DOWN to 87.3
WIDTH: rounded to 51.8, actual is between 51.75 and 51.84
51.75 is the lowest number it could be that would round it UP to 51.8
51.84 is the highest number it could be that would round DOWN to 51.8
To find the Area of the upper bound, multiply the highest possible length and the highest possible width:
A = 87.34 × 51.84 = 4527.7056
To find the Perimeter of the lower bound, calculate the perimeter using the lowest possible length and the lowest possible width:
P = 2(87.25 + 51.75) = 278
