Answer: Area (upper bound) = 4527.7056 cm²
Perimeter (lower bound) = 278 cm
<u>Step-by-step explanation:</u>
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
<em>87.25 is the lowest number it could be that would round it UP to 87.3</em>
<em>87.34 is the highest number it could be that would round DOWN to 87.3</em>
WIDTH: rounded to 51.8, actual is between 51.75 and 51.84
<em>51.75 is the lowest number it could be that would round it UP to 51.8</em>
<em>51.84 is the highest number it could be that would round DOWN to 51.8</em>
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
