#644" ft"^2#

The area of one of the triangular faces is given by #1/2 times 16" ft" times 14" ft" = 112" ft"#^2.

There are 4 such faces and one #14" ft" times 14" ft"# square base in the pyramid. So, the total surface area is

#4times 112" ft"^2+ (14" ft")^2= 448" ft"^2+196" ft"^2= 644" ft"^2#

I tried this:

You should have 4 triangles and one square (the base).
So the total area will be:

#"Area"=4*"Triangle"+"Square"#

#"Area"=4*("Base"xx"Height")/2+("Side"xx"Side")#

#"Area"=4*(14*16)/2+(14*14)=644"ft"^2#
