Mr. Anderson wants to decorate six of his windows with garland two of the windows are 3.4 feet 5.2 feet and the other four windows are 3.6 feet by 4.8 feet how many feet of garland are needed for all the windows

Respuesta :

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.
