Soal ini menggunakan perbandingan total asli = 72 total perbandingan = 3+4+5 =12 jadi p = (3/12)x72 =18 q = (4/12)x72 = 24 r = (5/12)x72 = 30 lalu luas = alaas x tinggi x 0,5 =p x q x 0,5 = 18x 24x0,5 ==== 216 cm2

kak caranya bisa dapat total asli itu gimana
total asli = 72
total perbandingan = 3+4+5 =12
jadi p = (3/12)x72 =18
q = (4/12)x72 = 24
r = (5/12)x72 = 30
lalu luas = alaas x tinggi x 0,5
=p x q x 0,5
= 18x 24x0,5
==== 216 cm2
