+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 If the PERIMETER Of the square is 144 each side is 144/4 = 36 units
then each SHORT side of the rectangles is 36/4 = 9
the LONG side of each rectangle is 36 also
so perimeter = 36 + 9 + 36 + 9 = 90 units
