Tolong dijawab ya! mksh
Jawaban:
Keliling = AB+BC+CD+DE+EF+FA
Keliling = 22+10+10+10+10+10
Keliling = 72 cm
[tex]luas \: = \: luas \: trapesium \: ABCF + \: luas \: persegi \: CDEF \\ \\ t = \sqrt{ {10}^{2} - {6}^{2} } = \sqrt{64} = 8cm \\ \\ luas \: = \frac{AB + CF}{2} \times t + CD \times DE \\ luas = \frac{22 + 10}{2} \times 8 + 10 \times 10 \\ luas \: = 128 + 100 \\ luas = 228 {cm}^{2} [/tex]
