okay you have two wall that are 40 feet wide and 16 foot high
so the area is 2 x 40 x 16 = 1280sq ft
you have 2 walls that are 60 ft wide and 16 foot high
so the area is 2 x 60 x 16 = 1920 sq ft
total 1280+ 1920 = 3,200sq ft
so the area is 2 x 40 x 16 = 1280sq ft

you should find the answer to be 3200ft^2 because 60*16=1920 and 40*16=1280 1280+1920=3200
