Answer:
the area of rectangle A is 133.33 sq cm
Step-by-step explanation:
let us suppose area of rectangle A be x....hence we get ,
3:5=80/x
or,3/5=80/x
or,3x=80*5
or,x=400/3
x=133.3.3
The directrix of the parabola is 
<h3>How to determine the equation of the directrix?</h3>
The parabola equation is given as:

A parabola is represented as:

By comparing both equations, we have:
4p = 1/4 ==> p = 1/16
-k= 3 ==> k = -3
The directrix is represented as:
y = k - p
So, we have:

Take the LCM

Evaluate

Hence, the directrix of the parabola is
