We know that the red line is f(x) and the blue line is g(x). Looking at the graph, we see that on the left, there's a section where the blue line is obviously above the red line and will be until negative infinity because the red line is continuously heading downward.
However, the points from the blue line to the right of that section are below the red line. So we know that we can't have any of those 4 points that are on or below the x-axis. Thus, P must be the topmost point.
Im guessing the question was what are the dimensions in cm... you just multiply each dimension by 40 to get: 2x40=80 cm by 1.5x40= 60 cm Final answer is: 80 cm by 60 cm
