Suppose that you measure a pen to be 10.8 cm long. convert this to meters. express the length in meters to three significant figures.

length of pen (in meters) = 0.108 meter

Explanation:

Given that,

length of the pen is = 10.8 centimeter

We will convert the given length centimeter to meter.

We know that,

1 meter = 100 centimeter

or

1 centimeter = 0.01 meter

2 centimeter  = 2*0.01 meters = 0.02 meter

Similarly,

10.8 centimeter = 10.8 * 0.01

10.8 centimeter = 0.108 meters

So, length of the pen  = 0.108 meter

Tha's the final answer.

I hope it will help you.

the answer for the second equation is (4,0)
