Area of a triangle = (½)*(base length)*(height; that is, "perpendicular height");
________________________________________________________
or: A = (½) * b * h ;
_________________________
Given: "b = 4.8 mm" ;
"h = (¾) * b = (¾)* (4.8 mm) = 3.6 mm ;
→ h = 3.6 mm ;
_____________________________________
→ A = (½) * b * h ;
= (½) * (4.8 mm) * (3.6 mm) ;
→ A = 8.64 mm² ; which is: Answer choice: [C] .

Answer:
You need to find the surface of each area and sum them up.
Step-by-step explanation:
You will need the surface area for each side.
So 2 up-bottom, 2 left-right and two front-back
2*(4*3) + 2*(2*4) + 2(3*2)
2*12 + 2*8 + 2*6
24 + 16 + 12
Total area = 52
