The area of a triangle is

\(Base * Height * \frac{1}{2}\)

*so for the smaller triangle we have *

\(2cm * 6cm *\frac{1}{2}\)

*equals*

**6 cm squared **

**The second triangle is **

**\(3cm * 7cm * \frac{1}{2}\) **

*equals *

\(10 \frac{1}{2}\)

squared inches and the diffrence is subtracting the smaller traingle from the bigger one whih equals

\(4 \frac{1}{2}\)
