Explicación paso a paso:
1. h=18/3
h=6
[tex]a=bxh\\a=18*6\\a=108cm^{2}[/tex]
2. D=9*3
D=27
[tex]a=\frac{D*d}{2} \\\\a=\frac{27*9}{2} \\\\a=121.5cm^{2}[/tex]
3. P=2b+2h
32=2(4)+2h
32=8+2h
24=2h
12=h
[tex]a=bxh\\a=4*12\\a=48cm^{2}[/tex]
4. [tex]a=\frac{b*h}{2}\\\\a=\frac{25*32}{2} \\\\a=400cm^{2}[/tex]
