Answer:
a=35x−x^2
Step-by-step explanation:
Having  
70 ft of fencing with a  
width of x
 feet and knowing the perimeter of a rectangle is  
p=2w+2l
we can state the length of the garden as:
70=2x+2l
and solving for  l
we know the length with be:
2l=70−2x or l=35−x  
And then knowing the formula for the area of a rectangle is  
a=w⋅l
we can write the equation as:
a=x⋅(35−x)a=35x−x^2
