Ginny has a sheet of plywood that 8s 4 feet by 8 feet. she wants to saw the plywood into pieces 1 foot high and 2 feet long for signs. hiw many signs can she make with the sheet of plywood

We start with a 4 by 8 foot sheet of plywood.  As the signs are to be 2 feet long, we divide 8 feet by 2 feet, obtaining 4 pieces of dimensions 2 feet by 4 feet.

We'll then cut four 2 foot by 1 foot pieces from each of those four 2 foot by 4 foot pieces; we end up with 16 pieces of size 1 by 2 feet.
