To construct a square with 1 meter on each side, we need to fill a 1 meter by 1 meter area with 1-fm squares. To find how many 1-fm squares this will take, we just use a simple dimensional analysis:
ANSWER: Therefore, we will need

squares each measuring 1 femtometer to construct a square with side 1 meter.
First compute the perimeter of the first two windows: (3.4+5.2)*2=17.2
The perimeter of the four other windows: (3.6+4.8)*2=16.8
The total number of feet needed for the first two windows:
17.2*2 = 34.4 feet
The total number of feet needed for the four windows:
16.8*4 = 67.2 feet
The total number of feet needed is then: 34.4 + 67.2 = 101.6 feet.
