[tex]1.a. luas = \frac{d1 \times d2}{2} = \frac{18 \times 12}{2} [/tex]
[tex]b.d2 = \frac{l \times 2}{d1} = \frac{192 \times 2}{24} = 16[/tex]
[tex]c. \: d1 = \frac{l \times 2}{d2} = \frac{384 \times 2}{24} = 32[/tex]
[tex]2. a. \: l = \frac{d1 \times d2}{2} = \frac{20 \times 15}{2} = 150[/tex]
[tex]b. \: d2 = \frac{l \times 2}{d1} = \frac{350 \times 2}{35} = 20[/tex]
