Question

Jocy is making a wooden picture frame that will have a width that is 12 inches shorter than its length. If he uses 100 inches of wood, what are the dimsensionsof th frame?

Answer 1

If he uses 100 inches of wood to make the frame, then 100 is double the sum of the length and the width, so 50 is the sum of the length and the width.

If the length is 12 more than the width, then the width is (50-12)/2=19. The length, then, is 19+12=31.
