Answer:
We know that since it's a square, the lenght size is the same on all sides. We can simply use pythagoras theorem:
a^2 + a^2 = 13.5^2
13.5^2 = 182,25
182,25 : 2 (because there are 2 'a') = 91,125
<u>The square root of 91,125 is 9,55 feet.</u>
we know all it's doing is adding 6 over again to each term to get the next one, so then
now for the explicit one
To simplify this fraction, multiply the entire fraction by the conjugate of the denominator. The conjugate of a square root and a number being added to it would be the number <em>subtracted </em>from the square root. In other words, the conjugate of would be
.
Applying that information to our fraction shown here, the conjugate of the denominator would be . We will multiply both the numerator and denominator of our original fraction by this expression to obtain our answer, as shown below.
Our answer is .
