[tex] \frac{1}{2} \times d1 = \sqrt{( { \frac{k}{4}) }^{2} - ( { \frac{d2}{2}) }^{2} } \\ \sqrt{( { \frac{104}{4} )}^{2} - ( { \frac{20}{2}) }^{2} } = \sqrt{ {26}^{2} - {10}^{2} } \\ \sqrt{676 - 100} = \sqrt{576} = 24 \: cm \\ \\ Luas \: belah \: ketupat \\ \frac{1}{2} \times d1 \times d2 \\ 24 \: cm\times 20 \: cm \\ 480 \: {cm}^{2} [/tex]
