The triangle in the front has base [tex]2+2[/tex] and height [tex]4.5[/tex] so area [tex]\frac 1 2(2+2)(4.5)[/tex]
The top fin is [tex]\frac 1 2(2.25+0.75)(3)[/tex]
The back fin is [tex]\frac 1 2(4.5)(3+5)[/tex]
The bottom fin [tex]\frac 1 2 (1+.5)(1)[/tex]
The back of the fish by the tail, [tex]\frac 1 2 (2+2)(4.5)[/tex]
The four little triangles, [tex]4 (\frac 1 2 )(.5)(1.5)[/tex]
Two thin rectangles, [tex]2(.5)(5)[/tex]
One big rectangle [tex](2+2)(1.5+5+1.5)[/tex]
Adding it all up
[tex]\frac 1 2 ( (2+2)(4.5) + (2.25+0.75)(3)+ (4.5)(3+5)+(1+.5)(1)+(2+2)(4.5)+4(.5)(1.5)) +2(.5)(5)+(2+2)(1.5+5+1.5) = 122.5[/tex]
Probably a mistake in there somewhere; check it good.
