Answer

$=0.164$ square units

Work Step by Step

We know that: $f(x)=x^2+3x+1$ We can use this to find the height of the rectangle by plugging in the left $x$ value, $0.2$: $height=f(0.2)=0.2^{2}+3(0.2)+1$ $=0.04+0.6+1$ $=1.64$ Thus the height of the rectangle is 1.64. The base of the rectangle is the difference in $x$ values from left to right: $base=0.3-0.2$ $=0.1$ Thus the area is: $Area=base*height$ $=0.1*1.64$ $=0.164$ square units
