Awindow is composed of 6 windowpanes. each has a length of 10 1/2 in. and a width of 7 1/4. what is the total area of glass in the window?

1 window pane :



6 window panes :



------------------------------------------------------
Total Area = 456 3/4 in²
------------------------------------------------------

If it is not required to do the question in fraction, it is actually easier if we convert everything to decimals first.

10 1/2 = 10.5
7 1/4 = 7.25

1 window pane = 10.5 x 7.25 = 76.125 in²
6 window panes = 76.125 x 6 = 456.75 in²

------------------------------------------------------
Total Area = 456.75 in²
