Suppose the weights (in grams) and lengths (in centimeters) of three groups of laboratory animals are given by matrix A, where column 1 gives the lengths and each row corresponds to one group.

If the increase in both weight and length over the next two weeks is 12% for group I, 5% for group II, and 3% for group III, then the increases in the measures during the 2 weeks can be found by computing GA, where

Find the matrix that gives the new weights and measures at the end of this period by computing , where is the 3×3 identity matrix.
