Suppose a farmer wants to fence off a rectangular area with three sides of a rectangle, using a river as the fourth side. he has 100 yards of fence to use. let x denote the length of the side of the rectangle parallel to the river. find a formula for the function a(x) that gives the area as a function of x. what is the domain of this function based on the formula and what is it based on the context of the problem?

Match the scale and the actual area to the area of the corresponding scale drawing. scale: 1 inch to 4 feet actual area: 128 square feet scale: 1 inch to 7 feet actual area: 147 square feet scale: 1 inch to 8 feet actual area: 256 square feet scale: 1 inch to 5 feet actual area: 225 square feet area of scale drawing scale and actual area scale drawing area: 3 square inches arrowright scale drawing area: 8 square inches arrowright scale drawing area: 4 square inches arrowright scale drawing area: 9 square inches arrowright
