Work Step by Step

We are asked to find the area of the triangular tooth for $b=5$ and $h=6$. We know that the area of a triangle can be calculated as $A=\frac{bh}{2}$. We can plug in directly to evaluate. $A=\frac{bh}{2}=\frac{5\times6}{2}=\frac{30}{2}=\frac{30\div2}{2\div2}=\frac{15}{1}=15$ square centimeters
