Step-by-step explanation:
One way to do it: The y-axis is the vertical axis. The point is at 4 on the y-axis.
Another way to do: Coordinates of the point = (2,4)
The y-coordinate is the second number.
1). Use the formula that has been developed for the surface area of that particular shape.
2). Break the shape down into pieces with shapes for which the formula
