Find the Lateral area for the regular pyramid. (Keep it as a Square Root)
Shtirlitz [24]

1. You must apply the following formula: 


 LA=<span>1/2 ×(Perimeter of the base)(Slant length)</span>

<span>
</span>

<span> 2. The slant length is (By </span><span> the Pythagorean Theorem):</span>

<span> a</span><span>^2=b^2+c^2</span>

<span> </span><span>a= b^2+c^2</span>

<span> a</span><span>=</span><span>√(</span><span>1^2+3^2)</span>

<span> </span><span>a=√10</span>

<span>
</span>

<span> 3. </span><span>The p</span><span>erimeter of the base is:</span>

<span>
</span>

<span> </span><span>P=2+2+2+2</span>

<span> </span><span>P=8</span>

<span>
</span>

<span> 4. </span><span>Then, you have:</span>

<span>
