Answer 3

\[ \color{dodgerblue}{\triangle}\color{lightskyblue}{A} \color{lightskyblue}{\scriptsize\text{rea}} =\frac{\color{chocolate}{b} \times \color{teal}{h}} {2} \]
use this formula for both triangles, and just find the difference

Answer 4

so it would be 2 x 6 / 2 for the first one

Four our 2nd triangle we would have
\(\color{chocolate}{b}=3cm\)
\( \color{teal}{h}=9cm \)

so
\[ \color{dodgerblue}{\triangle}\color{lightskyblue}{A} \color{lightskyblue}{\scriptsize\text{rea}} =\frac{\color{chocolate}{3} \times \color{teal}{9}} {2} \]
