a quilter wants to use as many of his 65 small fabric squares as possible to make one large square quilt .
A how many small squares can the quilter use ?
B how many small squares would he ahve left ?
C how many more squares would the quilter need to make the next largest possible square quilt ?

please explain :)

The largest square that can be made with what is available would use 8 x 8 = 64 squares. There would be one left over. The next larger size would be 9x9 = 81 squares, and your require 16 more.
