If a rectangle is graphed on a coordinate plane so that it has horizontal and vertical sides, what is true about the x- and y-coordinates of the rectangle's vertices?15 pts

Explanation:

Since the coordinates of the points on a vertical side are on the same x=constant line, they will have the same x-coordinate. Since the coordinates of the points on a horizontal side are on the same y=constant line, they will have the same y-coordinate.

If the horizontal sides of the rectangle are on lines y=y1 and y=y2, and the vertical sides are on the lines x=x1 and x=x2, then the four corner coordinates will be ...

  (x1, y1), (x1, y2), (x2, y2), (x2, y1)

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
