thank you

Let $x$ and $y$ be the length and the width of the pen, respectively. We have $2x+2y=100 \implies x+y=50$. We want to maximize the area, which is $xy=x(50-x)=50x-x^2$. The maximum value occurs at $50-2x=0 \implies x=25$. Sot he dimensions of the largest pen are $25\times25$.

$10\times10$ would be true if Mr. Alvirez has only 40 feet of fencing.
