Answer

$A=40$

Work Step by Step

We start with the equation for the area of a triangle: $A=\frac{bh}{2}$ We plug in the values for base and height: $A=\frac{16\times5}{2}$ To simplify, we follow the order of operations. First, we multiply above the fraction bar: $A=\frac{80}{2}$ Then, we divide: $A=40$
