Question

A rectangle with perimeter 44cm is partitioned into 5 congruent rectangles .The perimeter of each of the congruent rectangle is ?

Answer 1

That depends on the size of the large rectangle. If the width is x and the height is y, and the dividing lines are vertical, then each small rectangle has perimeter 2(x/5 + 2y)

So, for example, some dimensions below yield results of
20x2: 2(4+2) = 12
15x7: 2(3+7) = 20
10x12: 2(2+12) = 28
5x17: 2(1+17) = 36
