Answer:

A=2x(-x+50)

Step-by-step explanation:

Since there is a river, you only need to fence 3 sides of the rectangular area.

Let's name x the shorter side of the rectangular area. (height)

Hence, since we have 100 meters of fencing, the longer side of the rectangle would be 100-2x (base)

Area is base*height.

Hence, our equation would be:

A=x(100-2x)

Simplify

A=100x-2x^2

A=2x(-x+50)
