- The scale is 1 inch = 4 feet.
- The dimensions of the porch are 16 feet long and 12 feet wide.
First, we need to transform the length and width from feet to inches using the given scale.
Therefore, the scale dimensions of the porch are 4 inches long and 3 inches wide.
Additionally, we can find the new area, which is

- <u>You are right, the coordinates are</u>:
Explanation:
Here is how you can proove that you are right.
Note that m is the x-coordinate of the point . Since this point is to the left of the y-axis, it is a negative number, but the negative sign is included in
.
The distance from to the y-axis is not
but
.
That is the same distance from the point with the missing coordinates to the point (h,0).
Then, the missing x-coordinate is
Of course, there is not doubt about the y-coordinate: it is n, because the point with the missing coordinates is at the same height as (m,n).
Hence, the missing coordinates are x = h+m, and y = n: (h + m, n).
