#### Answer

$84 \text{ cm}= 2\text{ ft } 9\text{ in}$

#### Work Step by Step

If we want to convert from centimeters to inches, we have to consider the following conversion rate:
$ 2.54\text{ cm}=1\text{ in}$
We divide both sides by 2.54:
$ 1\text{ cm}=\frac{1}{2.54}\text{ in}$
We multiply both sides by $84$ in order to get the answer to the question:
$84 \text{ cm} =\frac{84}{2.54}\text{ in}\approx 33\text{ in}$
After that, we convert to feet and inches by using the conversion rate:
$1 \text{ ft}= 12\text{ in}$
We divide 33 by 12 with a remainder, in order to do the conversion:
$33=24+9=2\times 12 +9$
This means:
$33 \text{ in}= 2\times 12 \text{ in}+9\text{ in}=2\text{ ft } 9\text{ in}$
