keliling dan luas persegi 9 cm, 12 cm, 15 cm, 18 cm, 20 cm

semoga bisa membantu

Luas persegi = sisi.sisi = s²

L(a) = 9²
L(a) = 81
----------------------
L(b) = 12²
L(b) = 144
---------------------
L(c) = 15²
L(c) = 225
------------------
L(d) = 18²
L(d) = 324
--------------------
L(e) = 20²
L(e) = 400

Keliling Persegi = 4s

K(a) = 4.9
K(a) = 36
----------------------
K(b) = 4.12
K(b) = 48
---------------------
K(c) = 4.15
K(c) = 60
------------------
K(d) = 4.18
K(d) = 72
--------------------
K(e) = 4.20
K(e) = 80

semoga membantu :)
