By definition, the area under a complete density curve is equal to 1. So, the percent of the total area under a portion of the curve is equal to the area under that part of the curve.

We are looking for the area under the density curve when x > 3.

The area of a rectangle is length x breadth

So area = (3) \cdot (0.2) = 0.6

So the percent of the area under the density curve where x is more than 3 is 60%.
