A. panjang = = p = 25 x 800 = 20000 cm = 200 m lebar = = l = 10 x 800 = 8000 cm = 80 m b. K = 2 (p + l) = 2 (200 + 80) = 2 (280) = 560 m c. L = p x l = 200 x 80 = 16000
p = 25 x 800 = 20000 cm = 200 m
lebar = =
l = 10 x 800 = 8000 cm = 80 m
b. K = 2 (p + l)
= 2 (200 + 80)
= 2 (280)
= 560 m
c. L = p x l
= 200 x 80
= 16000
