2nd option is the correct answer.

5\frac{1}{3}\: units

Step-by-step explanation:

In\:\triangle XWZ, \: \angle XWZ= 90°\\ \: \&\: WY \perp XZ\\

Therefore, by geometric mean postulate:

WY^2 = XY\times YZ\\\therefore 4^2 = 3\times a\\\therefore 16 = 3a\therefore a = \frac{16}{3}\\\\\huge \red {\boxed {\therefore a = 5\frac{1}{3}\: units}}

erik [133]

Answer:

The 99th tower contains 9900 blocks.

Step-by-step explanation:

From the question given, we were told that the nth tower is formed by stacking n blocks on top of an n times n square of blocks. This implies that the number of blocks in n tower will be:

n + n²

Now let us use the diagram to validate the idea.

Tower 1:

n = 1

Number of blocks = 1 + 1² = 2

Tower 2:

Number of blocks = 2 + 2² = 6

Tower 3:

Number of blocks = 3 + 3² = 12

Using same idea, we can obtain the number of blocks in the 99th tower as follow:

Tower 99:

n = 99

Number of blocks = 99 + 99² = 9900

Therefore, the 99th tower contains 9900 blocks.
