Answer:
A) [tex] p r [/tex]
Step-by-step explanation:
The area [tex] A [/tex] of a rectangle can be calculated using the formula:
[tex] A = \text{length} \times \text{width} [/tex]
In this case, the length of the rectangle is the difference in [tex] x [/tex]-coordinates between [tex](0,0)[/tex] and [tex](p,0)[/tex], which is [tex] p - 0 = p [/tex].
The width of the rectangle is the difference in [tex] y [/tex]-coordinates between [tex](0,0)[/tex] and [tex](0,r)[/tex], which is [tex] r - 0 = r [/tex].
So, the area [tex] A [/tex] of the rectangle is:
[tex] A = p \times r [/tex]
