Arectangular beach resort is to fenced using 200 meters of fencing materials; no fence is required along the shoreline. let x be the length of each side perpendicular to the shoreline, express the number of square meter in the area of the beach resort as a function of x.

Let

x> the length of each side perpendicular to the shoreline

y> the width of the rectangular beach resort

A> area of the rectangular beach resort

P> fenced perimeter of the rectangular beach resort

we know that

A=x*y> equation 1

P=2x+y

P=200 m

2x+y=200> y=200-2x> equation 2

substitute equation 2 in equation 1

A=x*[200-2x]> A=200x-2x²

therefore

the answer is

A=-2x²+200x
