simple answer:
41.74m2

explanation:

lets take the front facing triangle.
its measurements are b=4.8m h=2.6m
and the formula for finding the area of a triangle is A=1/2bh
so 4.8*2.6=12.48
12.48/2=6.24
and we know there is a triangle of the same measurements on the other side so
6.24*2=12.48m2

then we'll do the same thing for the other sides
b=3.8m
h=2.9m
3.8*2.9=11.02
11.02/2=5.51
5.51*2=11.02m2

and the base of the triangular prism is a rectangle and the formula is A=bh
b=4.8m
h=3.8m
4.8*3.8=18.24m2

and to put it all together add them up
12.48+11.02=23.5
23.5+18.24=41.74m2

hope this helps!

Answer:

[tex]\large\boxed{41.74\ m^2}[/tex]

Step-by-step explanation:

We have the rectangle in the base and two pairs of the triangles.

The rectangle:

[tex]A_r=(4.8)(3.8)=18.24\ m^2[/tex]

The triangle 1:

[tex]A_{t1}=\dfrac{1}{2}(4.8)(2.6)=6.24\ m^2[/tex]

The triangle 2:

[tex]A_{t2}=\dfrac{1}{2}(3.8)(2.9)=5.51\ m^2[/tex]

The Surface Area of the rectangular pyramid:

[tex]S.A.=A_r+2A_{t1}+2A_{t2}\\\\S.A.=18.24+2\cdot6.24+2\cdot5.51=41.74\ m^2[/tex]
