Mathematical processes are the steps used to determine the result of operations
- The perimeter of the rectangle is

- The area of the rectangle is

The dimension of the rectangle is given as:


<u>(1) The perimeter of the triangle</u>
This is the sum of the side lengths of the rectangle.
So, we have:

This gives

Collect like terms

Open brackets

Hence, the perimeter of the rectangle is 
<u>(2) The area of the triangle</u>
This is the product of the dimensions of the rectangle.
So, we have:

This gives

Open brackets

Collect like terms


Hence, the area of the rectangle is

Hope i helped:D
seven less than the quotient of nineteen and a number.
Standard form is, hold a sec
x=2 is directix
that means it opens left or right
so we must use
(y-k)²=4p(x-h)
where vertex is (h,k) and p is distance from focus to vertex
also shortest distance from vertex to directix
the shortest distance from focus to directix is 2p
if p>0 then the parabola opens right
if p<0 then pareabola opens left
so
(-2,0) and x=2
the distance is 4
4/2=2
p=2
wait, positive or negative
focus is to the left of the directix so p is negative
p=-2
vertex is 2 to the right of the focus and 2 to the left of directix
vertex is (0,0)
so
(y-0)²=4(-2)(x-0) or
y²=-8x is da equation
not sure what form is standard tho
