solve area for one triangle multiply by 4 then add to area of square base
First: Find the area of the triangle first. (b*h)*1/2)*4
                                                              (14*9)*1/2)*4
                                                               252 squared feet
Second: Find the area of the square at the bottom. (L*W)-(9*9)=81 squared feet

Last: ADD IT!! 252+81=333 squared feet
SA=333
