That's not quite enough info. You need all 3 sides of the triangles & the length. let the sides of the triangles be a, b & c. Let the length br l

the 3 rectangles are al, bl & cl
you then have to find the areas of the triangles.

the total surface area is:
As=zl+bl+cl+2At where At is the area of the 2 triangles.
