+1245 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?
+37146 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
