a. Complete the table below for the possible dimensions of the rectangle and their
corresponding areas. The first column has been completed for you.
b. What is the largest area that you obtained?
c. What are the dimensions of a rectangle with the largest area?
d. The perimeter P of the given rectangle is 100. Make a mathematical statement
for the perimeter of the rectangle.
e. Simplify the obtained equation and solve for the length l of the rectangle in
terms of its width w.
f. Express the area A of a rectangle as a function of width w.
g. What kind of equation is the result?
h. Express the function in standard form. What is the vertex?

Answer:
b. 400m²
c.
d. the perimeter is 100. to find it's length and width you need to use the formula of 2(l+w)
e. P= 2(l+w)
100= 2(l+10)
100= 2l + 20
=2l + 20-100
-21= -80
-2l/-2= - 80/-2
l= 40
that's the only thing that i can remember I'm sorry but i hope it helps
