$e=12\ cm\\\\f=15\ cm\\\\P=\frac{e\ \cdot\ f}{2}\\\\P=\frac{12\cdot15}2\\\\P=6\cdot15\\\\P=90\ [cm^2]$

$a=7\ cm\\\\b=14\ cm\\\\h=6\ cm\\\\P=\frac{(a+b)\cdot\ h}{2}\\\\P=\frac{(6+14)\cdot6}2\\\\P=20\cdot3\\\\P=60\ [cm^2]$

$a=24\ cm\\\\h=5\ cm\\\\P=\frac{a\ \cdot\ h}2\\\\P=\frac{24\cdot5}2\\\\P=12\cdot5\\\\P=60\ [cm^2]$

a] P= 15 cm * 12 cm = 180 cm^2

b] P=0,5 * 6 cm * (7 cm + 14 cm) = 3cm * 21 cm = 63cm^2

c] P=0,5 * 24 cm * 5 cm = 60cm^2
