Answer:
x(34-x)
Step-by-step explanation:
the area of a rectangle is length times width. it is given that the length equals x. since all we need is one "width" and one "length" to complete the rectangle, all 34 feet of dividers are going to be used between the two sides. therefore, if length = x, then width = 34 - x, and area = x(34 - x)
