Tadi gambarnya terus soalnya : Jika keliling persegi 62 cm,nilai x yang memenuhi adalah.... a.5 c.12 b.9 d.1r

k = 2 X (p + l)
62 = 2 X ((3x+4) + (2x+2))
62 = 6x + 8 + 4x + 4
62 = 10x + 12
10x = 62 - 12
10x = 50
x = 50/10
x = 5

Keliling = 2p + 2l
62 cm = 2(3x + 4) + 2(2x + 2)
62 cm = 6x + 8 + 4x + 4
62 cm = 10x + 12
62 cm - 12 = 10x
50 cm/10 = x
5 cm = x (a)
