The square shown is divided into 4 congruent rectangles. If the perimeter of the square is 144 units, what is the perimeter of one of the four congruent rectangles?

Each side of the SQUARE is 12      (12 x 12 = 144)

so each short side of each rectangle is  (12/4) = 3

   the long side of the rectangles = 12    

     so perimeter of each rectangle = 12 +3 + 12 + 3 = 30 units

The area is 144, not the perimeter! Please help me more!

See revised answer with PERIMETER (NOT Area) = 144 units
