Jawaban Soal No. 15 n =umur nilah , m = umur maya n = 3m 2n + 5m = 132 2x3m + 5m = 132 6m+5m = 132 11m = 132 m = 12 n = 3m = 3 x 12= 36 m+n = 12 + 36 = 48
Jawaban Soal No. 17 p = l +3 K. Persegi panjang = 2 ( p+l) 54 = 2 ( p+l) 27 = p +l 27= l +3 + l 24 = 2l l = 12 , p = l+3 =12+3 =15 Luas = p x l = 12 x 15 = 180
n =umur nilah , m = umur maya
n = 3m
2n + 5m = 132
2x3m + 5m = 132
6m+5m = 132
11m = 132
m = 12
n = 3m = 3 x 12= 36
m+n = 12 + 36 = 48
Jawaban Soal No. 17
p = l +3
K. Persegi panjang = 2 ( p+l)
54 = 2 ( p+l)
27 = p +l
27= l +3 + l
24 = 2l
l = 12 , p = l+3 =12+3 =15
Luas = p x l = 12 x 15 = 180
