Area of the wall = 8 x 19 = 152 ft square
Area of the window = 4 x 5 = 20 ft square
Area of 3 windows = 20 x 3 = 60 ft square
The percent area of 3 windows from area of the wall = 60/152 or approximately .395 or 39.5%
This is the area of a triangle and a square
Area of a triangle is 1/2BH
here total height is 16 in triangle h is 16-10=6
base is 10
A=1/2*10*6
A=30 inch^2
Area of square=a^2
A2=10^2=100inches^2
A1+A2=100+30
130inches^2
-2/5 +1/2w = -6/7
move the -2/5 over by addition
1/2w = -16/35
w = -32/35
