[tex]luas = \frac{1}{2} \times a \times t[/tex]

[tex]~~~~~~~~~= \frac{1}{2} \times a \times \sqrt{s {}^{2} - ( \frac{a}{2} ) {}^{2} } [/tex]

[tex]~~~~~~~~~= \frac{1}{2} \times 12 \times \sqrt{10 {}^{2} - ( \frac{12}{2}) {}^{2} } [/tex]

[tex]~~~~~~~~~= 6 \times \sqrt{10 {}^{2} - 6 {}^{2} } [/tex]

[tex]~~~~~~~~~= 6 \times \sqrt{100 - 36} [/tex]

[tex]~~~~~~~~~= 6 \times \sqrt{64} [/tex]

[tex]~~~~~~~~~= 6 \times 8[/tex]
