The formula for the surface area of a triangle pyramid is shown below:
SA = A + (3/2)Bh 
Where SA for surface area, A=base are, b=base and h=height.
We can solve for surface are since all values needed are given.
SA = (0.07) + (3/2)*1.2*0.75
SA=1.42 square foot
Therefore, the surface area is 1.42 square foot.
