Answer 1

help plz

Answer 2

In general,
surface area means nothing but sum of all sides area....

In the given diagram...
there are 4 triangles....
area of triangle is A=(1/2)*base* height
so, hear A= (1/2)*3*6=9
hear there are 4 triangles so 4*9=36

one part is over.....

Now, see down there is square.....
area of square is s^2
so 3^2=9

so total area of pyramid is 36+9=45

that's it...
