Answer:

<h2>c. 16.5</h2>

Step-by-step explanation:

It's the right triangle.

The formula of an area of a right triangle:

A=\dfrac{(leg)(leg)}{2}

Look at the picture.

We have

leg=3,\ leg=11

Substitute:

A=\dfrac{(3)(11)}{2}=\dfrac{33}{2}=16.5

xy+4(20)>x-5y(4) 

xy+4(20)>x-20y 

xy+80>x-20y 

xy+20y+80>x 

y(x+20)>-80+x 

y>(-80+x)/(x+20)
