Last Math Help Question from Me for the Day... Hopefully!

<p>What about this one? Page 468 of the Blue Book. </p>

<p>It shows a stepped picture of blocks (1 block, 2 block, 3 blocks, 4 blocks).</p>

<ol>
<li>The figure above shows an arrangement of 10 squares, each with side of length k in inches. The perimeter of each figure is p inches. The area of the figure is a square inches. If p = a, what is the value of k? </li>
</ol>

<p>How would you solve this? Thanks!</p>

<p>I don’t know if my interpretation of the figure is right because I don’t have the BB, but I would think it is 20k+2k=p=a=10k<em>k=10</em>k^2?</p>

<p>either that or it is k^2=4k for one square.</p>

<p>Perimeter = Area</p>

<p>P = 16K
A = 10k^2</p>

<p>16K = 10K^2
16 = 10K
16/10 = K
1.6 = K</p>

<p>Was pretty simple.</p>
