Penjelasan dengan langkah-langkah:
16. A
L. persegi = sxs
= 36 x 36
= 1.296 cm²
L.segitiga siku" = 1/2 x a x t
= 1/2 x 15 x 36
= 270 cm²
L. gabungan 1.296 + 270 = 1.556 cm²
17. C
L.persegi panjang = p x l
= 9 x 25
= 225 cm²
jumlah sisi sejajar = (25-14) + 25
= 36
tinggi = 25-9
= 16
L.trapesium
288 cm²
L.gabungan = 225 + 288 = 513 cm²
