punten kak @kornelius82 bisa bantu gaa, satu soal sajaa :)
Jawaban:
Bangun Datar
Trapesium
Penjelasan dengan langkah-langkah:
BC = 141 cm, AD = 99 cm
DC : AD = 16 : 9
AB : AD = 20 : 9
AD = 9/(16+9) x total
99 = 9/25 x Total
Total = 99/(9/25)
= 99x(25/9)
= 11 x 25
= 275 cm
DC = 16/25 x 275
= 16 x 11
= 176 cm
AD = 9/(20+9) x total
99 = 9/29 x Total
Total = 99/(9/29)
= 99x(29/9)
= 11 x 29
= 319
AB = 20/29 x 319
= 20 x 11
= 220
Maka keliling trapesium
AB + BC + DC + AD
220 + 141 + 176 + 99
636 cm
