2) </span></span><span>4p * (y - k) = (x - h)^2 </span>
<span>(h , k) is the vertex </span>
<span>The vertex is halfway between the focus and the directrix (when they're at their closest) </span>
<span>p is that distance </span>

We know that
the area of a regular polygon is A=(1/2)*a*P
where
a is the apothem
and P is the perimeter
step 1
find the distance of the apothem
d=√[(y2-y1)²+(x2-x1)²]-----> d=√[(3)²+(-4)²]------> d=√25-----> d=5 units
A=(1/2)*a*P
a=5 units
P=40 units
A=(1/2)*5*40-----> A=100 units²
