The surface area of a shape is basically the sum of all the areas on a shape.
We’ve been given that the side is 17 mm.
An area of a square is A=s^2, in which s means side. So we do 17^2 to get the area of ONE of the squares.
Once we do that we get that the area of 1 square is 289.
Since there are 6 squares we need to multiply 289 by 6.
Therefore,
SA=1734mm^2
I'm pretty sure DEF is a scalene triangle since it looks like none of the sides are equal to each other.
Hope this helps!
