1) The length of the area should be at least 20 ft,

Call x the length and y the width

=>x ≥20

2) the distance around should be no more than 100 ft.

the distance around is the perimeter of the rectangle

perimeter = 2(length + width)=2length+2width

=>2x+2y≤100


System:

1) x ≥ 20
2) 2x + 2y ≤ 100

Answer:

The answer should be y is greater than or equal to 20. The equation should be 2x+2y is less than or equal to 100.
