The length of a rectangle is shown below:

if the area of the rectangle to be drawn is 20 square units, where should points c and d be located, if they lie vertically below the line that connects b and a, to make this rectangle?

c(−3, −2), d(1, −2)
c(−3, −1), d(1, −1)
c(−3, −7), d(1, −7)
c(−3, −5), d(1, −5)
