tolong di jawab dengan benar ya

a.
Nilai X
K = 2(p + l)
46 = 2(2x + 3 + x + 2)
46 = 2(2x + x + 3 + 2)
46 = 2(3x + 5)
46 = 6x + 10
46 - 10 = 6x
36 = 6x
6x = 36
x = 6

Panjang
p = 2x + 3
p = 12 + 3
p = 15 cm

Lebar
l = x + 2
l = 6 + 2
l = 8 cm

b.
Luas Persegi Panjang
L = pl
L = 15 × 8
L = 120 cm²

Maaf Kalau Salah
