Hey there!

 

Here, the Surface Area (SA) will be equal to the base + the three faces. We know the formula for the area of a triangle (\(\frac{Base*Height}{2}\)), so we get:

 

\(SA=6.9 + 3(\frac{4*7}{2})=...cm^2\)

 

Putting this into your calculator will give you your answer.

 

Let me know how you go :)
