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] .
