Answer:
A(w) = - + 100w
Step-by-step explanation:
First, we need to find down the length (l) of the rectangular area in term of w
We have 200 feet of fencing is the perimeter of the rectangular area, which mean:
2 (w + l) = 200
<=> l = 100-w
But the area of land: w*l
= w (100-w)
=- + 100w
So, A(w) = - + 100w
