Answer:
AB = 3.3 cm
Step-by-step explanation:
The formula to find out area of a regular octagon is given by
where a is the length of each side of the regular octagon.
Plugin A=54 into the formula
Divide both sides by 2
Plugin √2 as 1.41
Divide both sides by 2.41
Taking square root on both sides
a = 3.346
a = 3.3 cm (rounded to nearest tenth)
so, length of side AB = 3.3 cm

<u>Cubic Root </u>
The cubic root of a number N is M, if
It's usually tedious to manually compute cubic roots, but if we use some basic algebra concepts, the job is easily done.
Let's compute
The argument can be expressed in scientific notation as
The power of 10 has an exact cubic root since the exponent is a multiple of 3. To find the cubic root of the mantissa, we note it's the triple product of 17, i.e.
Thus our number is
We have then
