Question 436039
There are 4 walls to paint. The dimension that is common to
all 4 walls is the height, 9 ft.
wall #1:
{{{14*9 = 126}}} ft2
wall #2:
{{{ 12*9 = 108}}} ft2
wall #3:
{{{ 14*9 - 9*2 = 126 - 18}}}
{{{ 126 - 18 = 108}}} ft2
wall #4:
{{{ 12*9 - 3*6.5 = 108 - 19.5}}}
{{{ 108 - 19.5 = 88.5}}} ft2
The total area of the walls is:
{{{ 126 + 2*108 + 88.5 = 430.5}}} ft2
{{{430.5 - 400 = 30.5}}}
