Where n= the number of half-live that have passed. t 1/2 = half-life. For rock unit G the number of half-lives is three and therefore its age will be; 3 x 500 million years = 1500 million years. For rock unit D no half-life has taken place and hence its age is just its half-life (40 million years).

These rock types correspond to the Ferm Classification numbers.

Even without looking at boundaries, you may be able to see structure in a rock unit: the properties of many rocks vary with direction because the mineral grains are aligned with one another: we say the rock has fabric, another type of structure.
