A rectangle of perimeter 44 is partitioned into 5 congruent rectangles as indicated in the diagram. What would be the perimeter of each of the congruent rectangle.
Let the length of each small rectangle be L and breadth be B,
=== 2L==3B and 2*(L+B) + 2L + 3B = 44
solving we get B=4 and L=6
Hence perimeter of each small rectangle will be 2*(L+B)==2*(10)==20
