Answer

$A=170$

Work Step by Step

We start with the equation for the area of a trapezoid: $A=\frac{h(b_1+b_2)}{2}$ We plug in the values for the bases and height: $A=\frac{17(14+6)}{2}$ To simplify, we follow the order of operations. First, we must simplify above the fraction bar. To do so, first we add inside the parentheses: $A=\frac{17(20)}{2}$ Then, we multiply above the fraction bar: $A=\frac{340}{2}$ Then, we divide: $A=170$
