Answer:
Perimeter = 100mm
Area = 60mm
Step-by-step explanation:
P= (3x2) + (2x2) =10cm
10mm to 1cm
10cm x 10 = 100mm
A= b x h
= 3 x 2
=6cm
6x10=60mm
The vertex is always halfway between the focus and the directrix, and the parabola always curves away from the directrix, so I'll do a quick graph showing the focus, the directrix, and a rough idea of where the parabola.
<span>So the vertex, exactly between the focus and directrix, must be at <span>(h, k) = (1,
–2)</span><span>. The absolute value of </span>p<span> is the distance between the vertex and the focus and the distance between the vertex and the directrix. (The sign on </span>p<span>tells me which way the parabola faces.) Since the focus and directrix are two units apart, then this distance has to be one unit, so </span><span>| p | = 1</span>.<span>Since the focus is to the left of the vertex and directrix, then the parabola faces left (as I'd shown in my picture) and I get a negative value for </span>p<span>: </span><span>p = –1</span><span>. Since this is a "sideway" parabola, then the </span>y<span> part gets squared, rather than the </span>x<span> part. So the conics form of the equation must be:</span>(y<span> – (–2))2 = 4(–1)(x – 1)</span><span>, or </span><span>(y<span> + 2)</span>2<span> = –4(</span>x<span> – 1)</span></span>

The height will be 50.
To calculate area, you must know the base and height.
Since it’s already given to you, you must calculate it. Well... what times 1 gives me 50?
1x50=50
I think the answer is 716.7 not 100% positive
