Jawaban:
832 cm²
Penjelasan dengan langkah-langkah:
luas bangun = luas jajar genjang + luas layang2
luas layang =
[tex] \frac{d1 \times d2}{2} = \frac{(16 + 16) \times (12 + 20)}{2} = 512cm^{2} [/tex]
luas jajar genjang =
[tex]a \times t = 20 \times 16 = 320cm^{2} [/tex]
luas bangun = 512 + 320 = 832 cm²
