Question

What is the greatest possible error if Irina measured the length of her window as 3.35 feet?

Answer 1

The greatest possible error when measuring is considered to be one half of that measuring unit. For example, you measure a length to be 3.4 cm. Since the measurement was made to the nearest tenth, the greatest possible error will be half of one tenth, or 0.05.

Answer 2

Answer:

The greatest possible error for 3.35 feet is 0.005 feet.

Step-by-step explanation:

Given :  The length of window is 3.35 feet .

To find : Greatest possible error  

Solution :

The greatest possible error in a measurement is defined as half of the measuring unit.

3.35 feet is measured to the nearest hundredth of feet or 0.01 feet

Therefore, The greatest possible error is half of the measuring unit

$\frac{0.01}{2}=0.005$

So, the greatest possible error for 3.35 feet is 0.005 feet.
