tolong bantu kak, pakai cara ya
[tex]c = \sqrt{ {as}^{2} + {t}^{2} } = \sqrt{( {17 - 12)}^{2} + {12}^{2} } \\ \sqrt{25 + 144} = \sqrt{169} = 13 \\ \\ lp \: trapesium \\ tt(a + b) + tp(k) \\ 12(17 + 12) + 10(17 + 12 + 13 + 12) \\ 12(29) + 10(54) \\ 348+540=888 {cm}^{2} \\ \\ volume \: prisma \\ \frac{1}{2} \times t \times (a + b) \times tp \\ \frac{1}{2} \times 12 \times (17 + 12) \times 10 \\ 29 \times 60 \\ 1740 \: {cm}^{3} [/tex]
