58 = 2(3x - 2 + 2x + 1)
58 = 2(5x - 1)
58 = 10x - 2
58 + 2 = 10x
60 = 10x
6 = x
lebar = 2x + 1 = 2(6) + 1 = 12 + 1 = 13 cm
58 = 2(3x - 2 + 2x + 1)
29 = 3x - 2 + 2x + 1
29 = 5x - 1
29 + 1 = 5x - 1 + 1
30 = 5x
30/5 = 5x/5
6 = x
x = 6
l = 2x + 1
l = 2(6) + 1
l = 12 + 1
l = 13
Jadi, lebar persegi panjang tersebut adalah 13 cm
